One thing I haven't seen mentioned here yet............runway length. 3000', 5000', 6000'+...........

That's a lot of distance to be made up on the first few thousand that's right there when you have the longer ones. I might have to attempt this one day in the luscombe I borrow time to time, the bad thing is the climb-performance will keep me a little lower vs. distance, but makes it an equalizer to the event in which someone isn't expecting and/or prepared for such an instance.
