yes the use of some P/P 's are not allowed in NHB / UFC fights , and now that I've been training in KYUSHO for alittle while now and want to do some of this full contact fighting and workin these P/P's to fighting it is hard to hit the points that you need to to KO someone A. when you are moveing B. when the other person is traind in any other / or same style of MA,. if some jerk would come up and start in with me I would have the advantage cuz I know what I know & he dosen't but if we knew each other and he started with me he might know what I would do and defend aganst it .... element of surprise is the key to everything.................
