My 15 year old son plays the Volkl PB 7. I have been playing the Becker London, and string my son's PB 7's with the same set up I use. This is Volkl V-pro poly in the mains, and a multi in the crosses. I've tried my son's PB 7's a few times, but they felt a little more harsh than the London, and I've got elbow issues. Had an extra 7 unstrung and decided to try something different. Strung it with a full bed of multi (Gamma TNT Tour) very tight (68). Hit a little with it last night, and it felt pretty good. Seemed to be getting good spin, even with the multi. Anyone using the 7 have any recommendations of what string you are using? I thought it was too harsh to consider using with poly mains, and assumed all multi would not offer enough spin and control. Might still get that with a tight bed though. Insterested in what others may have found. Seems like a good racket for dubs, so would like to give it an extended try.
