I'm interested in trying the gut main/poly cross combo soon. I need a poly that will not crap out on me too quickly. I've tried full gut in the past and it felt a little too "trampoline-y" for me. I think the poly cross would help a bit with giving me a solid stringbed to work with with. I'm a flat hitter and I've always used thin poly in my Redondo and it's worked great, Kirschbaum Pro Line II 1.15mm to be exact but now I want some more feel just for fun and see how that goes. So basically now, I'm going to get a pack of Klip Legend 16 for the mains and I'm looking for a poly cross that has the best tension maintenance, feel, and hopefully keep its properties the best over time. I know it's wishful thinking and won't happen but I'm asking for what is best when comparing within polys. I know polys are not good for those characteristics but I'm asking for what's good relative to other polys. I want the poly there to provide stiffness to tame the gut down from too much trampoline feeling, a little more spin, and let the strings slide back into place. Being a flat hitter, I am not putting too much stress on my poly stringbeds so we don't have to worry about me snapping the strings in 3-4 hours like some people on these forums. This also tends to allow the strings to not go bad as quickly as it would for some other forumers.
