Thanks for the info, Paul, and sorry it took me so long to get back here to the forum...too many irons in the fire!
Yes, I agree that we all need to "standardize" the method of measuring/comparing angles, etc. when we discuss these matters. And in the matter of comparing our VERY similar (read: identical) airframes, the door bottom-to-float top is the one that should be used. As far as the angle of the step area on my floats is concerned, the top of the float is parallel to the bottom of the keel/skin for about the last 24" or so, so I doubt that that is very different between our set-ups. So at this point, I'll forget about the wing incident-to-float top comparison, and stick to the door frame bottom-to-float top comparison, and most likely increase that angle a bit when I reinstall the floats the next time....spring most likely.

I've been thinking lately that the most likely problem for this beast taking so long to lift off is the added weight of my CFI, (along with the short prop, low power, direct drive Jabiru power) which is about 235 lbs. If I could get my training revved up a bit in his Cub, and get his approval to cut me loose and fly the Kitox alone, I think the whole frustrating matter would be a thing of the past.

Again, thanks for all your help, Paul and others, and I hope that this thread hasn't scared off potential float flyers...my situation is kind of unique, I'm thinking.
