Hopefully he will be able to land a major contract deal now. Third place at the Arnold is a major achivement and I' m sure that a company will be sure to snap him up. Ok, the events of his past may be causing some companies to make the plunge. Personally, and seriously, I think that they can overcome this, and would probably increase sales of there products if, for the first time that Kai's in an ad, they make a passing referance to his past. For example, considering the creatine ads, asking what is the best sugar to mix it with for the most efficent delivery. They could go along the lines of "what would you mix your creatine with: grapefriut juice of dextrose?" with kai holding one in either hand with a thought bubble abouve his head. This type of humour would be well recieved and would probably knock the old stuff on the head for good, as it shows that it isn't taken too seriously. (PS, if this is ever used, remember that i want royalties!)
Either way, good luck to him and congratulations on his placing.
