Im curious how players arms, elbows & shoulders, using poly strings are holding up ? How long have you been playing poly strings and have these strings started causing you any arm problems ? I know these strings are great for control and ripping the felts but I personally cant use them, even when blended with natural gut and strung at low tension. Probably also depends on age since I was able to use kevlar blends for many years before doing damage and now needing to play soft strings. Im wondering how long some of the pro players will last, like Arod, who has already had a history of arm problems and I suspect his career will surely be shorted by playing poly strings.
