the thing is that no two bats are the same, this is because every cleft is different.
if you are looking for a big overdrived lump, you should say so.
the reality is that for 2lbs 8 oz bat you won't get a giant.
my suggestion is that you decide what shape you want and what, what your stickers you want, understand what your budget is then give this information to the sponsor and see if they can help you.
Think about having some sympathy for the sponsors, asking for all this information is a little nuts in my view.
having 35mm edges or 38mm edges won't make a difference to you. what will help you is getting a bat in the shape that will help you the most.
I agree that you should know where the middle position is on the bat.
