One more thing to consider would be the pitches in your thumb hole. I used to "top" the ball as a result of squeezing. Because of the anatomy of my hand, I found after considerable experimentation that I had too much reverse pitch, as well as too much palm pitch. I had so much trouble staying under and behind the ball with my hand, that I decided to make a change.
I moved slowly from 3/8 reverse and 3/8 palm pitch to 1/4 forward and 1/8 away pitch. Now I have no trouble staying under and behind the ball without squeezing the hell out of it, and with practice I have developed a much cleaner release. The result is more speed and power at the pins than I ever had before I learned about thumb pitches.
By the way I do wear a brace, the Eagle 3 adjustable brace. It is very restrictive to someone who isn't used to it, but because I have used the same one for so long, I have learned to adjust release types with and without adjusting the amount of cup on the brace.
I have a feeling that if I moved even more forward with my thumb pitch and possibly even more away, I might be able to ditch the brace and get similar ball reaction, but I don't want to spend hundreds of dollars to change out all of my equipment when what I do now is pretty effective.
Everyone is different, so what I did may or may not work for you, but it is one more variable to play with if the mood so strikes you.
