Are butt caps attached to the handle with a staple, or glued, or what? I have a wiggle in the butt cap of my Head Pro Tour 280 MP. I assume the butt cap is cracked and needs replacing. I don't want to take the grip apart until I know what type of job is required. Any help? Also, if I get the butt cap off and discover that the handle material underneath the butt cap is the problem, i.e., cracked, broken, is there anyway to get the actual handle material fixed? Thanks in advance.
