<<but having 2-3 year trained black belts teaching Kempo instead of 20-30 year trained people seems a big problem.>>

regarding teachers who have been teaching for "20-30" years. 17-18 or 27-28 years ago they too had only been teaching for 2-3 years.

start your own style neil, i think this or mma are the only things that will make you happy. well maybe not mma since you would have to learn their fundamantals and drills etc ... neiltaokoushu would be a great name for it ...
