I have my Biomimetic 100's at 372g (13.12oz). I use lead tape around the inside of the head from 9 to 3. I use several layers, first is Babolat for a heavy base, than 2 to 3 layers of standard 1/4".
The specs say 11.8oz (334g) strung, but all of mine weighed in at 11.9oz (337g). Specs say the swing weight is 311, so with the extra ounce and a third, I'm sure it is way more than that.
The combination of the 59 stiffness and the low tension seems ideal for my game.
Evil doers ... you face The Tick!
