I prefer one stick but train two for the coordination they engender. There are historical references of Filipinosa armed with two sticks as well as bolos. In the Balangiga Massecre (Samar) the locals used bolos smuggled into town hidden in the coffins of dead babies but several of the Insurrectos also used double sticks, I believe they were Kamagong and more flat shaped than round in cross section. I interviewed several old guys there who had relatives who had fought in the battle and one swore his great uncle had used two sticks.
Pigafetta's account of the Battle of Mactan refers to the natives using fire hardened sticks of spear length but also two sticks of shorter length. Most translations of his account of the voyage of Magellan don;t mention this but I have read one that said this openly. I am in the provinces and don't have access to my hard drive with the references or my Balangiga article but when I return I am happy to hunt for them for the dubious.
Having said all that, I think the actual use of two sticks is minor. Most would use a blade and there are plenty of blades here, always have been. I nearly bought a striking Sandung in the Bogo market for three bucks the other day but I already have several and how many can you use at one time anyway?
As for the old car aerial trick, have you ev er tried to rip one off in a hurry while some clown is wailing away at you? So you have an aerial, oooh, I'm scared! I was once attacked with a CB antenna which was far more whippy but I took it off him and threw it away, not worth using. Where I live there are always local newspapers lying around uncollected, they make a far more effective weapon than a car aerial.
