What is the best wrist brace to give more forward end over end roll?

Ron Clifton's site shows different hand positions "finger dancing" and the ball roll that they equal.  I find a Mongoose with finger strap can help in this kind of release.  Say you want more forward roll.  Take the Mongoose finger strap over your middle and ring finger with the index finger a slight distance from the middle maybe 1/4" apart and take your little or pinky finger and spread it wider or further from your ring about 1".  This will cause more forward and less side roll, axis rotation will be less.  It's the 5th pic down in Ron's article.  You can play with your index and pinky fingers and get a wide range of ball motion.  This in general has been lost as bowlers change balls rather than change hand or release positions. 

To do any of these hand position and release changes easily one would need very good ball fit.
