View Full Version : Dunlop Bio 400 Tour comfort

I was testing the Dunlop Bio 400 Tour and was wondering if it would be hard on the arm. I loved the racket but I don't want to purchase it if it will cause arm problems in the long run. Anyone know?

Sorry for the triple post but thats the Dunlop Aerogel 4D 3Hundred tour. Any different than the bio 400 tour?
