My favorite poly is Black Magic. It retains playabilty for a long time and is very soft for a poly. So I am searching for the ultimate cross string to hybrid it with in my PK 7G. My target tension is around 56 to 58#s. First up is 16 gauge gosen OG Sheep Micro. Right off the bat, I knew this was an easy go to setup. Awesome feel, great feedback and decent spin. This setup surprised me and has lasted 8 hours before snapping. Ironically, the Black Magic went first but the OGSM was on it's way as well. This durability may be due to the tighter pattern in the sweet spot area of the racquet, which I prefer. If you have a more open pattern racquet, I would expect to get 4-6 hours instead of 8-10. Cons are that around 6 hour mark, the setup gets a little mushy and drops tension about 10 pounds. The spin potential is average. I generate my own spin so this setup was sufficient. My last session I purposely hit flatter balls at the opponent for a bit before dialing up a little more spin. Once I went more low to high the spin was still there and threw off his timing a lot for easy mishit errors. I would rate the spin production about a 6/10. All in all, this is an easy go to hybrid setup that will cost you around $6. I have now strung up Dunlop Hexy Fibre as my next cross. It is strung up at 58#s and that will be my next playtest. My 2nd racquet will be strung up with Mantis comfort a little lower at 56#s. I will have that one ready to play next to the Hexy Fibre in a multi cross showdown.
