I just broke a set of Hurricane/XCel strings. They were strung at 60/57 on my Wilson (see signature). I was wondering, after two weeks of no play, how much tension will this hybrid drop? Anyone have experience? Also, I'm planning on stringing my Wilson with Wilson NXT Tour 18/ALU Power Rough 16L @ 58/55lbs. I'm afraid that the initial loss in tension for the ALU will be too much. Should I string it higher? Thanks guys.
