Hey Everyone, Here's a brief summary of the problem: I play with a Head Microgel Extreme and recently had the racquet strung with Head RIP Control at 60lbs. Played with these strings at that tension for two weeks now (Playing 4 times) and have noticed my elbow progressively getting stiffer and sorer...Previous to that had the racquet strung at 55lbs but was way to loose for my liking with many balls flying long.Thought i'd string it at a higher tension for a little more control.Think it may have been a mistake due to my elbow. Picked up yesterday a Head Microgel Prestige Pro that i need to string and am hoping that it may be a little more forving on my joints as its not as stiff as the extreme. ADVICE NEEDED on a suitable string(or stick with RIP control)and or tension to save my joints! Feed back will be much appreciated!
