My normal racket is a LM Radical OS, but last night I got to play a game with a Yonex V-Con 15. According to TW, the Radical is rated as LOW powered, and the V-Con as LOW-MED powered. However when playing I found (and so did everyone else) that the Radical has WAY more power than the V-Con. It also has same, if not tighter strings. Can anyone explain?
