I've been doing some research and it seems that "Timothy D. Waid" only started studying Pekiti-Tirsia in 88. "Bill McGrath" seems to have trained much earlier in 1975. Tom Bisio and Bill McGrath seems to be the two prodigies of Pekiti-Tirsia. Bisio having left Pekiti-Tirsia to study San Miguel Eskrima and Ba Gua, with Bill McGrath to be left as the most senior of the Pekiti-Tirsia members. What's boggling my mind is how Timothy D. Waid was chosen as "succesor." ???
I imagine McGrath (who IMHO does have the complete system of Pekiti-Tirsia) started studying with other kali teachers, and Gaje did not appreciate this (which seems typical with the elders in the martial arts subculture). I imagine Gaje pretty much screwed McGrath out of his rightful position as succesor because he didn't approve of McGrath cross training with other teachers, and gave succesorship to Timothy Waid.
Can anyone else clarify on this? Does my theory sound about right, or am I off?
