I am a 3.5 baseline grinding lefty who uses a Prince EXO Tour 100 16/18. I was hitting well, using "smart target" strategy, and hanging with 4.0 players. I wanted to hit w/more pace, especially on my forehand, so I went from 56 lbs. of string tension down to 53lbs. I cannot keep my shots in with this tension; they are always 1-3 feet out. I am thinking of perhaps going to a Head racket with the same head size and length, but much stiffer; for more power. What are your thoughts? Return to 56 lbs. or try a stiffer racket? Thanks.
