Okay, I've made up my mind based on this logic:
Team 1 is speed but lacks power (Lee)
Team 2 fights to win, not to kill (Boyka)
Team 3 fights like art with grace (Jet)
Team 4 fights to kill, kill, and kill some mo'. (Jaa)
If Jai & Boyka had killing intentions with their size, I would easily give it to them.
