I want to do a lux/tecnifibre hybrid in my wilson 6.1 classic. I am going to use tec. on the mains and lux on the crosses. I normally string at 52 lbs w/ tecnifibre biphase 16g. My question is...How much lower should I go for the lux on the crosses without going to low? Maybe 49 or 50 lbs? While maintaining my normal 52 on the mains.
