You're right, shortstripper. I was already worked up over the huge fuss everyone is making of the AOA/stall-speed thing. (It's such a simple concept.)
My apologies, Miserlou.
I will say though, that I don't see anything wrong with pushing the airplane down with a full slip at higher than normal approach speeds. It bleeds off more energy in a shorter distance, and will give you the same landing roll if you're doing it right (not carrying extra speed as you get to the runway). In fact, you're less likely to end up carrying extra speed because you'll have bled off that energy earlier in the approach.
The alternative of doing it at normal approach speeds (basically best-glide speed), will give you a shallower angle of descent. At slower than normal approach speed, you'll again get better angle of descent, but you're flirting with a stall.
