Hi Jon, thanks for your response. Given that Chris has taken to copoly at rather high tensions lately to tame the liveliness of open-patterned racquets I guess I should have guessed he'd find MonogutZX too lively.
I agree that the TWU numbers are very interesting for this string, it's just a bit stiffer than natural gut. My thinking is that if a player can control a full bed of natural gut then a full bed of ZX should be controllable too. If Chris or any of the other playtesters feel like comparing ZX to gut in terms of power, shot trajectory and control I'd much appreciate reading it.
