I get why a hitter might want a heavier bat, but not really why theyd want one with a heavier pickup, what have I missed?🤔

Always thought the idea that 'hitters' want heavier weight/pickup bats and 'touch' players want lighter is a really weird generalisation, doesn't make any sense to me. Fairly confident that Rahul Dravid's (for example) bats would be a heavier pickup than David Warner's!

Suppose some players lose the feel with a really light pick up, wasn't that supposedly why Tendulkar used such big bats?

Does the size or strength of the individual not have a say of how the pick up feels?

I use heavy bats - 2.15+ - but also want them with low middle which means they will pick up heavy for their weight.  I find that I play too early and lose shape with bats that feel lighter in the hands.  I also go against the modern trend for light bats and faster bat speed and focus instead on maintaining shape and making a good contact.  As ever, it is case of experimenting with different set ups to find what works

Think he always used heavier bats having grown up, playing with his older brothers bats.

Yeah but I think the reason for sticking with them is that lighter bats didn't feel right in his swing, which would be one explanation for why a player might prefer a heavier pickup.

Top work mate, great review. Huge fan of those photos on the reflective table surface as well.

(Musical Instrument-wise) Heathen! It's a piano! :D Thanks for taking the time to read. :) Glad you like the photos! Just need to get a nicer camera now rather than just snapping them all on my phone!


Absolutely love mine! Picks up so much better than my PE Stokes did... mine weighs just under 2.8 (when I weighed Wednesday) and picks up like a wand, right up my street. Also have a bat on order which is similar shape so will be interesting to compare.

Top photos as per @Chad

Yeah, they definitely do feel lighter than the dead weight suggests - the Stokes generally feel how you'd expect them to, which isn't surprising given the size and position of the swell! I'd be interested to see what your ordered @e4sby :D


Comparison with Ben Stoke's model is a good idea.

Chroma's shape looks like the shape of bats used by Virat Kohli. Or am I off here?

Very similar - a lot of pros use pretty similar profiles these days! I think the Keeley Superior is also another bat which is similar, which I believe was based off the Kohli profile too. (Could be talking rubbish)


Good to see that piano back in vogue 👍

Need to get it tuned and played, and also give it a good wipe/dust!


An excellent review as usual@ @Chad. Do we see a possible Phantom Anniversary edition bat review soon from you?

Not reviewed my Phantom stuff yet even after a couple of years! (I'm guessing the ball may have hinted that I bought a Phantom recently - I haven't!) I'm not too sure I'll go for a 5 year Anniversary bat for 550 though... (I do have a nice 150 anniversary bat to share sometime though) It looks nice, but not quite my cup of tea... Even with a cricket bat addict like me, you'd be hard pressed to find me paying that much for a sticker up company. Not that there's anything wrong with that, but for me, it'd be spent on a bat from a brand that makes their own bats.

@Chad here you go...

Bought from Talent Cricket had a choice of 4 which all weighed around 2.8. The cleanest one was snapped up minutes after I saw the photos so settled for this beauty.




Weighs a smidge under 2.8, will be adding a hex grip instead of these new lighter grips so expect bat to weigh 2.8.5 after. Hoping pick up improves further when grip is added. Going to take some dislodging for next seasons match bat although I do have one on the way...

Firstly, thanks Chad for the excellent and most thorough review - much appreciated :)
But if I may,
Pickup.  It's always grated with me!  I've thought about this ever since discovering this forum, as it's always mentioned in any review, but it's always 'subjective'.
As you mentioned, GM have attempted to clarify this with their pickup index, but how does that relate to any other bat that isn't manufactured or indexed by GM?  Again, lots of room for personal opinions and guesses.
Why not take that huge grey area out, and replace it with something that's black and white?

'Pickup' is a function of three simple measurements - length, mass, and point of balance.
Point of Balance is easily measured by placing the bat across a cylindrical object (such as a horizontal beer can) and rolling it until the POB is found, mark the point and measure from there to the tip of the handle.
Measure the entire length of the bat, and divide POB measurement by this.  You now have POB as a %, which is indicative of where the middle is.
Multiplying the POB % by the mass of the bat will give a meaningful measurement of what it will feel like in your hands.

For example, a 'high middle' bat might have a total length of 848mm, POB at 480mm, weight 1180g, so 480/848= POB% at .566 X 1180g = a pickup value of 667,
a 'Low middle' bat might have the same length and weight, but POB at 520, so 520/848=POB% at .613 x 1180g = a pickup value of 723,
and a junior size 6 'mid middle' bat having POB 462mm, length 790mm gives it POB% of .585  X 921g = a pickup value of 538

It all seems so simple to me, I can help but wonder why nobody's ever used anything similar before?

Again, superb review, with great pics and information - thanks Chad.
I'm not directing this specifically at you, but at the forum in general.



I agree and disagree. Those 3 measurements are very much things you can measure, of which most batmakers will give you 2 of. You could nail all 3 of those things between 2 bats, yet have a different pickup for you. You can change the grip on a bat, with one of the same weight, and the pick-up will feel different. The thickness of the handle - some people will have smaller hands, and feel that a thicker handle actually makes the pick up feel worse for them, and some bigger hands. We also all grip the bat differently. Double gripping tends to make the pick up feel lighter - but you're still having to pick up the same amount of mass. Sure, it changes the balance point a bit, but it could be that your hands don't have to be so tense cause the grip is thicker, so could make it feel that bit better for you

Heck, we even had a wee exercise here, where we all measured the weight of our bats from the tip of the handle and from the tip of the toe, while suspending the opposite end at the same height. Result? Gave a rough indication of what did feel lighter etc, but there were some variances.

IMO, you don't want to confuse the buyer too much, and I feel GM probably provide the best indication of how a bat will feel compared to others.

For me, I've always taken the GM Pick Up Index to be roughly this, based on my experience. (What I'd expect a neutrally balanced bat to feel at these weights - again, what is neutral?)

1 - Anything up to 2lb 7oz.
2 - 2lb 8oz - 2lb 10oz.
3 - 2lb 10-11.
4 - 2lb 12-13
5 - 2lb 14 +


I understand that buying blind is often one of the most frustrating things, as you're depending on the seller to give an indication of how the pick up is like in their hands. IMO, the best thing you can do is make sure you have a dead weight range that you're comfortable with. Never go beyond this, and don't go for anything too silly like a 40mm toe bat with a middle 2 inches off the toe and no wood in the shoulders. At the same time, don't dismiss something too soon just because your old bat picked up fractionally better - muscle memory can do wondrous things.

If you're a double gripper and buying in person, buy a bat which picks up well with 1 grip, that advice seems to work best when people come round to pick up something from my collection.

I'm sure on the factory tour they showed mechanism which determines the index... they had calibrated it somehow...

It certainly wasn't done on weight alone.

True.  I guess in my definition of 'pickup' I'm more concerned with the way the bat reacts with gravity and the laws of physics, than what how a grip 'feels' in someone's hands. 
Regarding people gripping the bat differently (in their hands), when an individual compares bats they would use the same grip, so that wouldn't be a variable, but yes, I couldn't argue that what feels 2-10 to me, must feel 2-10 to someone else.
The whole point was to separate opinion from facts.  If you can see or feel a difference, then you should be able to measure it.

I fail to see any logic in how adding more mass of another grip could possibly make a bat feel lighter, but if somebody feels that is true through their own hands, who am I to tell them what they feel? :)
I thought double (and tripple) gripping was all because Clive Lloyd used to do it, and everyone wanted to be more like him -  Guilty as charged :D

Interesting discussion anyway - thanks for the reply.
