I've been reading Dave Patrick's book, "Aerobatics for everyone". He alludes to the fact that with exponential you may not need dual rates at all.

I just bought my first computer radio, so I'm curious how the pilots here do it? Do you use expo and dual rates, or just expo?

I really like the idea of not using dual rates. Being the forgetful SOB that I am, I can see myself being on low rates when I should be on high, or visa versa very often.
