nothing wrong in doing yaw yan and muay thai, the knowledge you have the better you are as a fighter. Before i got into muay thai, i trained in kickboxing. When i spar against fellow team mates in class i combine both kickboxing and muay thai and surprise my team mates when i do axe kicks and hook kicks at them, since alot assume i'd be doing low kicks on them. but i agree it would be nice to see yaw yan fighters fight in mma or K1, i'm really like the hybrid yaw yan
