Hey all, Finally got a chance to hit last night with polylon sp strung on my Prince Triple Threat Ultralite. Observations: For heavy/spin hitters, this string is great. The ball really flies off your racquet. First thing I noticed is that my serves were going long. Ground strokes go further and with more spin. My arm also felt a little sore after awhile. I think I'm going to try a hybrid next and see if that helps any with the comfort. I can't compare this string with others, so right now I will probably stick with the Micro even if I have to string my racquet more often. I've been using the Gamma Ruff strings on my backup racquet for over a month and those have yet to break,..seems like I have lost a bit of tension on them, but they sure do hold up well. I remember the first couple times out those strings felt pretty good. PAIN in the butt to string with them, though.. Anyone have any other suggestions for strings to try? So far between Gosen Micro and PSGD I would have to give a slight edge to the Gosen for playability.
