If you are using a weapon capable of taking a man out with one shot, I don't think grappling is your first choice of techniques in combat. Obviously a sword, but even an ironwood stick against an unarmored man, makes for a much different fight than armored and using rattan. However, when your opponant closes the gap and tries to smother you in a clinch, then grappling comes into its own.
What you often see in sparing is this progression:
1.Striking at range.
2.Whoever is not doing well at long range tries to smother, clinching and trying to tie up the opponant's weapon arm while throwing shots with whichever limb is not involved with the clinch.
3.Grappling to defeat the clinch.
Kind of a "Rock-Paper-Scissors" thing.
Disarms were traditionally the last thing taught in Pekiti-Tirsia single stick because you needed to have so much else under your belt in order to pull them off (and even then, only after a good strike or two.
Ron Harris (the guy with the Tapado stick on the Dog Bros tape) gave an introductory Tapado class one afternoon at the 1988 Pekiti-Tirsia summer camp in Nashville, TN. Tapado uses a stick of about 1.25" in diamiter and about heart height. I'm 6'1" and this gives me a Tapodo stick of about 4.5 feet. The main moves I was shown are a backhand and downward strike that springs back off the ground for an uppercut,(however I have seen video of the chief Tadado instructor in the Philippines using many more strikes than just these two).
Tapada uses a thinner, more whippy stick of about 1" and is measured to the same height as the user (I would use a 6'1" Tapada stick). Tapada's main moves are a forehand downward hit and a veriety of uppercuts. My instructor, Tuhon Leo Gaje, was taught Tapada on a trip to the Philippines back in the late 1970's and taught it to our group in NYC.
I think both Tapada and Tapado are expressions of different dialects and come from the same root meaning "to hit".
