Nice flying Cappy, you have some pretty nice skills[8D]. You ought to put all of those nice maneuvers together in freestyle routine. If you combined them together you would have a great routine.

I totally agree, the coupling is not linear, so it depends on your speed and angle of attack during this. The only way to somewhat rectify this is to program a multipoint mix....for me, thats too much trouble. I prefer to "feel" the plane during this maneuver and lean slightly on the sticks ever so gently to make corrections. I also like to enter these from what I call a "death slide" ( not sure if that's really what it's called).
My buddy started calling it a "suicide slide" last year. I dont think it really has a name but its a cool thing to do.
I also like to use a multipoint mix for knife edge , but like youI dont consider high alpha in that mix. I just deal with the corrections in high alpha.
