any other besides these styles

i was just wondering if there was any other style that uses pressure point techniques other than phenoix eye, egale claw, double phenoix, and panther fist?

I'm not really too sure what the techniques you described are, but I think I can safely say there are loads more techniques that can be used. A PP is no different from any other target, so basically if it fits, stick it in there! (Shoshin - no wise cracks)

Edit - Just done a look on the web found out for myself. Chinese Martial Arts have so much cooler names for their moves than the Japanese. In answer to your question I'll refer to my original answer above - Yep, if it fits stick it in there!

Was there a particular point you were looking at hitting, because the target will always dictate the strike you use?

I think most styles use pressure points. Whether they realize it or not is a different story.
