Well i have my 1st ever stringing machine right next to me and im well chuffed Anyway let me get on with the questions . . 1) I currently use BB/Syn Gut @ 54lbs. I break these every other week and is gettin rather expensive. I used to play with Syn Gut @ 56 lbs all over. Would i loose anything from making this switch again ? 2) stringing friends racquets, i dont no exactly what tension they have it strung at, is there a general tension you restring racquets at ?
