To the OPs original point the sweet spot on most bats to the average player will be pretty much the same on all bats, pressing these days is generally pretty good across all bats and brands in my opinion. Tapping up an old ball will give you a gauge as to if its a plank but nothing more.
Until you play it in and use it for a period of time you wont know how good the ping really is and even then there will be little difference in my opinion.

Reckon Iv had 2 actual planks in 15 or so years.

But I've ALWAYS enjoyed yours. Where've you been?  :D

I didnt name any names did I? But if the cap fits, wear it I guess...

And glad you missed me

So, I think a mallet is good for finding out how wide and long the sweet spot is. You do the trick of holding close to the bat face, hitting gently with the mallet and seeing if you get a fast vibration of the mallet over a wide area.

Second though, the speed of a ball off the bat definitely determines how high the ball bounces, unless you have imparted some strange spin that changes the aerodynamics. Can give the equation if you like, but it's not very helpful.

Finally, yes I agree that an old ball is best for judging the pinginess off the sweet spot. But, interesting question is whether some bats work better with new balls that worn balls. Could be, say, that hard pressed bats are better for openers and soft bats for middle orders. Anyone got any opinions or evidence about that?

Nah, spotted your punter mentality miles away. Can't say you stand out.

None of us ever have evidence for the nonsense we spout 😅

Its quite simple really. v 2−v 1=−e(u 2−u 1)

I would go one further and say that in this case speed off the bat is the ONLY factor that determines how high the ball bounces.  Gravity is constant.  The properties of the ball are constant.  Drag is relative to speed.  The equations are helpful as they prove it beyond any doubt.

Yes, totally agree. The only reason I mentioned spin is because this could change the air drag coefficient because of turbulence etc. But I'm sure that is not making a difference here.

True, and you also need conservation of momentum to solve the equations. But given any particular speed of the ball after hitting the bat, the height it reaches will be the same whichever bat you use

Surely the only true measure is a bats ability to hit a ball repeatedly into a ceiling?
