Re: Strings and shoulder pain
strings generally vibrate at a low frequency, so are rarely the cause of shoulder pain. it is the high frequency racket vibrations that usually cause pain. however, kevlar is so stiff it is one of the only strings that causes problems. it is always advised that you should string kevlar 10% lower than to compensate. but really, kevlar should only be used by chronic strings breakers, who cant get any durability out of any other string. let me put it this way, i'm thinking of stringing up a kevlar/natural gut hybrid in my prince graphite mid at 30lbs, about half my normal tension.
