I don't know where else to ask this. The Dog Brothers teach stick fighting, and I know they're listed as a system that uses Pekiti Tirsia. I've read that Marc Denny has trained with / maybe still trains with Guro Dan Inosanto. The thing that confuses me is that nowhere on the Dog Brothers' site do they list Marc Denny's credentials. Other instructors have theirs listed, but not Marc Denny. He's listed as Punong Guro, but under whom? I know my lineage. I can't seem to find his, and I'm wondering if I should bother with their material. I mean no disrespect. The man can obviously fight, but as a more traditionally schooled martial artist, lineages are important to me.
