I took 3 ounce of my old laver, ,it had stood unused for two seasons after ordering it, due to being way too heavy for me at 2.12
I just thought sod it one day, it cost me a fortune,and it's just sat there, might as well take it to work and start sanding weight off the back,(it had stupid edges,and a massive spine)
I just kept sanding, then trying pick up, until it felt right
First seasons use with it, I averaged 48, over 600 runs scored, , Job done
You may be able to hit the gym a bit, ,but, a decent bat maker will be able to reduce the weight a little off the bat
Grips and lead tape? Hmmm
