How arm frinedly are the Prince Graphite Classic (Original) midplus racquets? the flex rate is 66. i could lead it up though. Since I have never had any ellbow problems and could play with stiff racquets for hours withouth any pain the POG should be fine, or? however, I would like to play with a higher tension like 63-65. I don't think that TE problems are permanent. if i should experience any pain i could pause and switch the racquet. any people with TE experience?
