If the mass of both the concaved bat and traditional bat is the same, the momentum of the bat in a given shot will be the same, therefore giving the same momentum to the ball. Bigger edges will reduce how easily the bat rotates when hit nearer the edge of the blade making the ball more likely to go in the intended direction.
thats clever to explain force = mass * acceleration. which is correct. providing both bats have exactly the same mass (as you say weight) and have the same centre of gravity (sweet spot location). The only thing that is left is the transfer of energy from both the bats from 1) the centre 2) to off centre i.le edges... in the case of 1) the I'm not aware of any test done to say in either way, but in the case of 2) i know the concaving bat will retain its structural rigifty more in off centre shots. so for off centre shots its better. most those shots may not make bulk of the shots so is it worth it.
Thanks for this video Paul. Great explanation. I think the unfortunate thing is that it is only people that really think about their cricket that understand what you mean. I was speaking to a guy at cricket the other day, who had been playing cricket for years, you didn't understand why bulk made huge concaving was a bad thing.
Zhafran Azhar not at all. My concaving is very gentle so not much difference in them but if you take the extreme concaving that many major companies do you have taken the majority of the guts out of the hitting area. That's why I've used my knowledge as a professional cricketer as a coach and put them in to my bat making skills
