My current frames strung with overgrip are 345g and 32cm balance, so have provided the unstrung specs to him based on what i use.
Also for his reference, he asked me to estimate the swingweight of my current frames using the TW method. Its a strung with overgrip SW so not ideal for him, but gives him a ballpark. Dont know how accurate it is but did it a few times and took the average and the SW came in at 354. I have happily used frames with lower swing weights and am open to this so will see what options he can provide based on lead placement.
