I have also replied to this thread to showcase a couple of videos. the first is of Telesporo SubingSubing, a lesser-known martial artist in the FMA community. Mr. SubingSubing comes from Mindanao and some say that he taught a certain Mr. John Lacoste (who later settled in california and ended up teaching Mr Dan Inosanto) his style of fighting (The name of which has been lost and which many have dubbed simply as 'Moro-moro style').
Well, this looks very Visayan to me. (BTW, I love the way he moves!)
AFAIK, Telesporo SubingSubing came from Balamban, Cebu. There are some old Visayan outposts on Mindanao and during the last century many Visayans settled throughout Mindanao. From all accounts there is no open teaching of any traditional Moro MA/Silat on this island (if any); the Sulu archipelago might be a better place to look for genuine Moro MA but even there you'd have to be careful not to run into Visayan MA nowadays...
