Let me qualify my question with my pool "status": I have only been playing regularly for about six months. I play and practice every day, and have seen some great improvement in that time. I am able to consistently park whitey on the break... can consistently pocket balls at medium power or less. Which leads me to my problem, despite all my practice, I have made very little progress on shots where power is needed. What are some of the common mistakes that are made when hitting with power? I feel like my stroke is the same when a put some "juice" on the ball, but I am obviously doing something differently as I am so inconsistent when I put muscle into it. Any advice would be greatly appreciated.
