In Filipino Martial Culture (Mark. V Wiley) there is a chapter on Binas Dynamic Arnis and an interview with their grandmaster Herminio Binas. Within the interview, Binas states that he taught Jerson Tortal (Sr.) Also interesting is the fact that I stumbled upon a document on the internet which focused on Vinas Lapu Lapu Kali/Arnis. The founder of which was Jose Vinas...Herminio Binas's cousin. He also stated that he taught Jerson Tortal and Leo Gaje as well. I believe all these men were from Bacolod City, Negros. Can anyone clarify this link between these grandmasters? Anymore information would be interesting. Thanks.
