Actually if I can recall my "unwanted" mantis days well, one dominate strategy of mantis fighting is enter with 3 or 5 punch/kick movement combinations and then retreat back and begin for the set up of another 3 or 5 movement combinations. These drills often were learned before we even touched a form.
Generally, the mantis player enters gets something and then exits and sets up for the next entrance. We used to train for gripping strength not for qinna but for going in gouging eyes, strike throat, pull ears, pull flesh of face, grab hair, pull flesh of inner thigh and groin area, kick groin area and then out---hopefully you brought something home metaphorically speaking.
No criticism on my part---these guys look very good to me. If I recall, Brendan Tunks was on the same trip as I was in 1998 or 2000 in Qingdao---I think he and his group ended up in Yan Tai and I am sure he has studied with some real top people in Yan Tai/Qing Dao---in addition to whatever else he has added.
