I just need an advice. I'm playing with Head Liquidmetal Instinct at the moment. I'm on good semi-pro level. In the past I had a problem with my elbow, but I lowered the string tension a little bit and the problem occures very rarely now. I'm rather offensive ground-stroke player with long swing. I wanna change a racqet and I'm considering Microgel Instinct but due to my offensive style I'm thinking of upgrading to Microgel Prestige MidPlus (98 sq. in). Do you think I would benefit from changing to Prestige MidPlus, would it improve my gameplay and would it cause any problems with my elbow?
