The best switch I ever made was when I was still a very green beginner.
I was progressing very quickly, and began playing opponents who hit harder. I had 110 sq. inch Prince that was all of 9 ounces. That racquet was so light, it twisted in my hands after a ROS no matter how tightly I held it. I got a 100 sq. inch Head that was an ounce and a half heavier, and my game stopped going into its slump and immediately came out of it.
I never used a "player's racquet" because they've always been too heavy for me. I only used what worked, and that happened to be the most random Head racquet practically built for me.
I am an unpredictable player. Even I surprise myself with some of the shots I make.
