just a quick two cents. I've used about five polys or so and right now I'm using Unique and Signum in two different racquets. I've used the Unique a few times. Even though Signum feels soft it simply is just a tad too harsh for my arm. So I'm done using a full poly setup unless it is with Unique strings but I think I'm going to hybrid those too even though I've found them to be the most comfortable poly. So anyone out there who wants to try a poly give one or two a try. But if it hurts then GO TO A Hybrid or no poly altogether.
