Hi guys, just wondering whether i should use RPM Blast full. I am very cautious of tennis elbow. Currently I am using RPM at 55 and Technifibre NRGs at 57 on the crosses. I am a junior player 14 years old (turning 15 next week and ranked top 25 in the Eastern section) and I am very small (5"4 106 lbs). Im just considering going full RPM because I want a little more pop and spin on the ball because I use an eastern grip on the forehand. If anybody has any other suggestions for strings I would highly appreciate it as well. However I do not want tennis elbow for sure. That is the main goal, thanks.
