I am intrigued but, if open hand is so much better why don't wee see it in cage fights?
Isn't that where most of these things work themselves out?
Simple. two reason 1) the tape wrap makes the wrist very stiff, 2) palm strikes make it to easy to stick a finger in your opponents eye which will get you a DQ. If you look though you will see some open hand work in MMA. There was a double palm being used on A.Silva in his last fight for example.
