FYI s_mma_tfc.tbm is the same as s_mma_wip4.tbm but without the logo in the dojo. We were having some issues with peoples feet getting stuck in it. the tfc version has better reactiontime and matchframe settings as well.
For people just getting into the MMA scene and want to learn grappling these two are good:
s_wrestlewip17.tbm - less realistic but easy to learn grappling fundamentals like hooks, leg takedowns, and throws.
rain_freestyle_wip3.tbm - same tori's as s_mma_tfc_.tbm but without any points or cage. good for wrestling/submission practice.
