Hi everyone, I've got a Prince Ozone Pro Tour, no customization. I'm around a 4.0 all-court player looking for a string with (in order of preference): 1. Tension retention 2. Increased spin potential 3. Not a crazy high price I don't break strings. My past experiences include Prince Recoil at mid tension (lost tension in like 3 days haha), and Prince Synthetic Gut Multi at 60lbs (been in the racquet for probably 5 months now ). I was thinking about trying out a full set of MSV Focus Hex 17L (1.18) or Signum Poly Pro Plasma 17L (1.18). I'm trying to stay away from any really harsh strings, but I'm OK with any suggestions or recommendations. Thanks!
