I was playing with Head RIP control and I really liked the feel I got from the string. The only problem was, I broke the string in 7 hours. Considering the fact that it is (always) the cross that snaps first I was thinking if I should use a poly as a cross. As much as I have read the playability shouldn't change much. I am using Head Radical MP. Rip Control was strung at 25/24 kg (55/53 lbs) - gauge 16 (1.30). Which poly(s) do you recommend for hybrid and what should be the recommend tension - gauge 17 (1.23)? Thanks for your replies.
