Back in the days of the 10 speeds, a rider had to do a few double shifts to get progression. That meant he had to shift both the derailer and the chain rings. Really dumb IMO.
As I have posted before especially if you have a front triple, look at it this way. Granny for hills, center ring for most riding, and the big ring for down hills or with the wind. Pick one of the three and simply shift across the rear cluster. That may not work well on some short chain stay DF bikes but it does work well on bents.
