I'm currently playing with 4 Prince Warrior 100 ESP frames (14/16). 2 sticks are strung at 46/42 (revolve spin 16/ Volk cyclone 16) and the others are at 42/38. The launch angle is higher but I can instinctively keep the ball lower if someone comes to net. The higher launch angle actually bothers some players as it's not easy hitting higher arching balls with nasty topspin earlier. What I have discovered is that I can't be lazy with my footwork and really need to commit to every shot or the balls can fly long. I get longer string life by stringing lower and it's more comfortable on the arm. Volleys took a little time to get used to. It's winter here in Asia right now so I might have to reassess string tension when the temp goes up in the spring. I play on clay at the 5.0 level.
