I started playing with the POG OG five years ago, when shoulder, elbow, wrist, all were hurting. Either the racquet helped, or my form improved, but there was a great improvement. However, I felt loss of power. I am middle age plus 3.5 -4.0 player, and need the extra power. I am an all court player. I demoed many racquets, and liked especially the Vockel C!0, and the Prince NXG OS. Any suggestions? my criteria is: easy on your arm, control, power.
