Good critique.
I am gonna have to go out and try it [img]/ubbthreads/images/icons/smile.gif[/img]

I dont recall having to pitch down more than when I went into the slip.
It seems to me that adding drag just increases the descent rate.. (maybe AIS a little) and thats why you use it. Have you ever used a slip to slow down? its always used to GET DOWN (forward slip that is) and I am not an aero-phys guy, but in practice, since I use slips to get down, not SLOW down.. by proxy thats my understanding of the effect of the drag.
One of my worries is that the answer to this issue also involves where you are on the power curve. Its too late in the eveining to hypothesize this at this time.. stay tuned.
