I don't think it's an exaggeration, direct relationships are found with:Originally Posted by arnisador
There are a lot of arts which claimed ties to Doce Pares prior to GM Diony Canete and GM Cacoy Canete coming to the US to teach. Most notably those were Villabrille Kali and Serrada. GM Villabrille even claimed to have been a champion and founding member by some accounts although he was never in any of the club records. Felicimo Dizon who trained Angel Cabales claimed to be in Doce Pares although there were no records of him there as anything but an observer at a match or two. So there was some exaggeration. Although since the early 1990's those claims have been redirected to a hitherto unknown "other" Doce Pares club. That may be the case.
Doce Pares isn't the wellspring of all of the FMA but it has had influence on a lot of styles even when it wasn't a direct relation such as in:
Lapunti Arnis de Abanico
Doce Pares as a collection of styles has evolved over the years and there were always many branches. Although Balintawak or Modern Arnis might not look like a Doce Pares you've seen, there are many Doce Pares you haven't. Plus what it looks like now may not be what it looked like in the past.
