I have been stringing my own racquets for about six or eight months now and I restring them after every 10-15 hours of play. I would like to try playing with gut. I was curious, how long could I expect the string to last? I am a 3.5 player, all courter, and I play 1-2 times a week indoors and outdoors on hardcourts, singles and doubles leagues. I play a couple of local tournaments a year. On a good week, in addition to playing 1-2 times, I may get an hour of serving practice in as well (flat,topspin,slice & amer.twist). I break mains using Xcel Premium after two weeks (yes, I am from the dark side! PD+ OS @ 57lbs.) so I switched to Syntronic Brio and the durability is much better. I don't crush the ball, but I can hit with decent pace for a 3.5. Could I expect more than two weeks play at a 3.5 level with gut? Heat and humidity will rear its ugly head in a few months too. Thanks in advance for any assistance.
