Which one would you pick to hybrid with synthetic gut: Tourna Big Hitter Silver (NOT ROUGH!) or Mantis Power Polyester. Here's the thing.. One teaching pro at my local club has two kids, one boy (13) and a girl (10), and both of them have great strokes and have good national rankings for their age. The kids just hit the crap out of the ball. They both use Luxilon Adrenaline 1.25 the boy on a Head Youtek Extreme Lite, and the girl on a Head Youtek Radical Lite. Today i was hitting some serves with the boy and he was cringing on the serves. I asked him what was wrong with him today. He said is elbow was hurting, and i asked him where, he point to his Lateral epicondyle. Later he broke the string, and i asked him how long was he using that stringjob, and he said 2 weeks, but he was playing 2/3 hours a day with it. I went to talk with his dad about it, and he said he didn't had a clue about strings and just bought a reel of Adrenaline because everyone uses Luxilon, and thanked me for my concern. I also said that for the price of Luxilon Adrenaline he would be better of with Tourna Big Hitter Silver or Mantis Power Polyester, and he should hybrid them with synthetic gut to soften the stringbed a little. He was very interested and he asked me to send him some deals on the polys i suggested. I've tried MPP and i know it's comfortable for a poly and maintains tension fairly well, but i don't know anything about the TBHS. Can someone who used both of them enlighten me?
