So the 62/57lb (gut/poly) went flat really fast. Very boardy. Decided maybe I'll just find a good poly and restring every 2 weeks. I do like polys, they just crap out too fast. Strung one up (330g) with Luxilon ALU Power at 52lbs. Never played with it, but do like 4g. What I noticed was it was super buttery, maybe a little to much pop. I could focus on making a smooth technically correct stroke and the strings would create depth and pace, balls would look they were going long and then just dip down inside the baseline. This was amazing .... UNTIL.... we started playing a match. Then I started sailing them. Switched over to the boardy gut/poly hybrid and started being able to smack the fuzz off of them. The reality is however, I think if I just upped the 52lb LUXILON a hair and focused on my stroke mechanics, I would end up with a heavier ball and be better of as far as my strokes. My serves were insane by the way. Feel like I am inching closer to my perfect racquet/string combo. I have a buddy who often jokes "Remember, its not the arrow its the Indian "
