I string my own racquet with my ATS Super Stringer 2 (cheap drop weight much like a Gamma X-2). Currently, I use a hybrid with poly in the mains (a generic that I quite liked, comparing head-to-head with Lux. BB power; 16 ga.) strung at 50 lbs and Prince Syn. gut in the crosses at 65 lbs; 16 ga. My racquet is a Babolat AeroPro Control. I play mainly a baseline game. 4.5 player. Good, hard serve. I was considering trying natural gut in place of the Prince in the crosses. 1) Is there anything special I should know about stringing natural gut? 2) Does it need to be "pre-stretched"? If so, how should I do this? 3) What brand would you recommend? Babolat VS? Babolat Tonic+? Klip Legend? Since switching to this hybrid setup and going with the 50 / 65 tension setup, I rarely break strings. I usually cut them out before they break. When I used a full Prince Syn. Gut setup at 65 lbs, I broke strings fairly often. Thanks in advance for answering my questions.
