I believe the origins of ti to be related to pankration.
But as I have stated the scant evidence I have to date tells me that Medulant is correct in his assumptions about grappling in karate.
ROFL. Wait......your "scant evidence" of pankration's link to Okinawan karate is because medulanet said so?! This is the research you have done?
And who mentioned pankration in the first place....?
