Hummm, good video, thanks for posting, but listening to it I find myself wondering why not just buy type III? It does all the others do only better... That being said, I use the original mostly. Not sure why, may it is cheaper,, fits my personality.
One thing I do know, I like the Titebond best of any brands I have tried. I bought a bottle of Klingspor white (yellow) glue and it works but not as good as Titebond in my opinion.
