ahh 4bt n 5bt windmills.. fun stuff. if you're doing it forward, you're pretty much doin the same exact movent as a wallplane weave, but instead of plantin your arm under your arm pit.. keep it with your other hand (this is the 4th or 5th beat depending) then throw that shit straight in front of you (on the audiences plane of course) once ya figure that out, forward and reverse comes easy.
as far as your butterfly buzzsaw fountain, how are you doing it? are you doing it with the same motion as a regular fountain(as in goin from the side to lower front to your other side then to top front?) or like a butterfly fountain??<--which is the correct way of doin it (p.s. ive done this in on of my older vids

)
either way congrats! i remember when i learned all that mumbo jumbo, most of it all came in on one day like yours did lol.
