I know that rattan is the traditional weapon for FMA (among others of course) and that kamagong and other hard woods are used. Studying under Grand Master Estalilla and Sigung Ed Bansuelo, we use dense plastic sticks (white - not sure what they are called and black delrin). We use these as they are pretty much indestructible and provide a pretty good weight (once you get used to them) for siniwali drills. We tend to use 20" for some Serrada (Cabales-Davis-Bansuelo), 30" for solo and doble baston work, 36" for some larga mano work. These are 1" diameter sticks. We also use 1.5" diameter 48-60" sticks to emulate the bankaw and sibat. (Watching GM Estalilla with a sibat and bankaw is amazing!) Does anyone else use non traditional sticks for training?
