How does it affect the rebound? If the cleft is low-density and a bat weight 2-10, one bat is thinner (old fashioned) and the other is a lot thicker, does this affect how the ball rebounds? Is energy transfer or vibration of the thicker bat (albeit low density) greater than the thinner bat? I don't think F=MA fully explains the characteristic of the rebound since the low-density bat has a larger surface area, more air-pockets in the willow for compression/decompression, and overall more flexibility in the wood to create the whippy affect. It is like a trampoline and wooden board (of same weight) but trampoline generates a lot higher bounce.
Thoughts?
Experiences?
-
In my experience thicker bats/lower density clefts do not rebound better than more traditional shapes. The difference i have found is when I edge it it goes further.
-
I have two bats same weight one is a lot smaller than the other but is a better bat
Different makers granted,
The only way tk Test this would be to have one bat maker make two bats same weight different density in the same day with the same tools etc then have an hour on a Boeing machine etc

Surface area?! Nothing to do with it. Air pockets - errr, no? More flexibility - quite the opposite, a thicker cross-sectional area will be more resistant to bending, ie. stiffer. Stiffer means less energy lost in deformation = more energy transferred to the ball = ball goes further. For the differences you're talking in cricket bats though, this isn't going to make a big difference.

^^ I agree. Thicker edges will make a difference as they will minimize bat rotation.
To your comparison of trampoline and wooden plank - they are made of completely different materials.
The "air pockets" reference makes sense but the dry bat fibers are quite rigid to have large compression and de-compression to get the trampoline effect.
In my opinion, ball hit from the middle of two bats of equal wieght should travel same distance assuming they pressed the same etc etc

Isn't that the theory behind the GN scooped bats? Are those bats really rockets? Lot of people like them.

I meant for off center shots, thicker edges might have an advantage..... Never used scoop and not sure i will like it either :)

I don’t agree with the thicker edges prevent twisting theory since if you have same amount of wood in both bats on their edges, both bats should respond the same way for twist. Further, the twist can be reduced by simply having a pronounced oval handle. Air pockets in the bats don’t matter either but what matters the most is what is the characters of the 1 cm face thick face of a bat. Does it have enough rebound in it caused by moderate pressing? If pressed too hard (or knocked using a metal hammer), that bounce/ rebound reduces leading to poor performance. In my opinion, thicker bats only provide psychological advantage and that’s all!

Distribution of more mass around the edges improves the response to an off-centre impact, which is the (well-proven) theory behind the Scoop. Just bigger edges won't necessarily have the same effect, and certainly not to anywhere near the same extent. Handle shape doesn't make a blind bit of difference, the ball has already left the bat by the time your hands get involved.

You mean 1cm from the surface of the face to the bat down towards the core?

Yes. i mean 1 cm towards the core of the bat.
I also believe that if thick edge (pressed lightly) and thin edge (pressed heavily with a curved faced roller) should perform the same as long as the amount of wood on the edges is same in both cases.

According to new ICC regulations, a batsman is allowed to use a 3 lb, 40 edge monster but can't use a 2-8, 41 edge bat. And this is to restore the balance in favor of the bowler! So at least what the ICC thinks on this matter is pretty clear!

Bat speed has a fair amount to do with it. And to be fair timing. A heavy bat is only useful in the hands of someone with the strength/timing to wield it.

This is true. There is an optimum middle between weight and bat speed for each individual where they can hit sixes with the max possible weighted bat they can wield and swing to produce a certain bat speed. In a coaching video that I saw, the coach said that you need 80+ mph bat speed to hit the ball 90 yards.

From the experience with the bats i have i can confirm that Bigger size bats pings & perform better than the smaller size bats of same weight.
I have 5 bats with same 2-13 weight and but different sizes. Here are the rating performance wise
GN Signature (51 edge and 75 spine)
B3 Warner Replica (50 edge and 70 spine)
Kook Obscene (48 edge and 70 spine)
Aldred Velocity (35 edge and 60 spine)
B3 TKC (43 edge and 65 spine)
Hope this helps.

I may be wrong (I normally am), but I recall seeing a post or something on the internet. Its was to do with the height of the spine, and were the ball is struck, to optimise the response of a shot it should be in the middle and struck at the highest point of the spine. This was to do with the vibration from where the ball strikes the bat which goes to the back of the bat (spine) and then back to the face.
Without finding the thread or site I have no prof and I am by no means a scientist. I don't think it is the density of the bat but the volume of wood from the face to the spine.
You can then go into pressing - but I do not know much about that.

This is a good point. What you are describing is the same principle behind a golf driver.
