I don't mess around with dual rates either. I just leave everything with 100% throw on all surfaces. I then use as much stick input as needed. At least this is what I do with my Stik.

I'm building an Extreme Flight Edge 540 and the throws are crazy. Elevator will nearly do 90 degrees if setup properly. Anyway, I'm told to definitely setup dual rates and lots of expo with this model, so I'm going to have to learn it eventually.
