Anyone know anything about the Head Pyramid Tour MidPlus? I have a friend who just gave me two to string up and he asked me my opinion of the racquets. They look to be pretty high quality graphite, and were made in Austria. What is the actual head size, it does not say on the frame? Were these player racquets? He is a good 4.0 player and is trying to determine if he needs to be switching racquets. Any help would be appreciated.
