The Wai Kru is slightly different from camp to camp. The T.B.A. does it different than Fairtex, each Kru or Ajarn will have his own ritual. I am surprised that this guy has little more experience than you and doesn't have his camps Wai Kru, why is he your coach? BIG SUGGESTION, don't just borrow some other camps Wai Kru from video or books without sometype of association to it. I have done less than a handfull of different Wai Kru (3) and wouldn't do the Master K Wai Kru at a T.B.A. function, or visa versa. FIND A KRU! If you just pick one from the internet as a resource that you don't know or are not associated with the camp who's Wai Kru you are using can make you and your COACH look like chumps not champs. Sorry for sounding so critical, but the Wai Kru is no joking matter to Ajarns, Krus and heads of real Muay Thai associations. It's like not being part of the military and saluting everywhere, or not being a member of the Catholic Church and blessing everyone. The Wai Kru is not a costume to be put on to look more like you know true Muay Thai. Find a legit Kru. PEACE
BTW, If your coach and you just grab any resource for a Wai Kru and you adopt it, remember the Wai Kru pays respect to a proper Kru(COACH), do not do a Wai Kru for someone who is not truly worthy, especialy a Wai Kru of a camp you are not apart of.
