Sambo is my favorite, the gravity helps you not fly off, and it is just great. Wushu is fun too, because you can do crazy flyin moves.
Sambo. It's a great base for making fun out of such as headpassing, sparring and break dancing in single player & multi player.

Also any teamwork parkour mods. It always feels good to work together with other guys to complete a track.
