Red Alert! If you fly with minimal throws make sure that when you come in to land, that you have enough elev. to flair--- In other words set-up your dual rates so you can have a little more on launch (to correct from left thrust prob.) and more on landings when there is LITTLE air moving over your control surf.
While in flight tiny throws are enough for most-
I have never tried 100% expo. (maybe 40%) but I am used to small control movements (read- finger movements-) and I like having a ton for landing and for fast rolls- I even have triple rates on my 9C but I cant say I use 'em all the time-
