Hey guys, just wanted to know if there is anybody out there that breaks strings often... EVEN these Luxilon strings that are supposed to be very durable? I break these strings a lot. One string job will last at most 3.5hours. I am a hard hitting 5.0 (at least my forehand is a 5.0 forehand). Anybody has this problem as well? I Love these strings but I cant understand why they last a lot longer for other people. Thanks!
