I've tried a ton of polys and keep coming back to Hyper G just because of how predictable it is and relatively long lasting compared to the Blasts and 4Gs. 17 in an 18X20 (GTour) at 52 lbs, I hit heavy spin from the baseline and like the reliable control at the net with that tension; no elbow issues most of the time unless I'm playing 4 or 5 times a week. Played 16 when I was still using 16X19 (Speed), strung a bit higher, but something totally off about the L, for me, in any setup at any tension. As someone said earlier, no "perfect" string, people just like what they like. Also, I think it is funny to be hung up on how a string looks. Purely utilitarian; if it does the job well, it could look like feces and I wouldn't mind.
