Speaking from experience, that Ritchey with the 94bcd is not going to give you a good chainline as a double unless you get something very small. People always throw out numbers for the Road & the 110bcd Triple & I promise that it's different. I'm running one with a 46/30 combo on my old Atlantis & a 103 puts in in a barely useable range that I probably still shouldn't be running. The best advice I found, searching through a lot of old messageboards, was to try to find an old Phil Wood or cup & cone in the upper 90s. I'm actually going to change mine back into a triple for all of the above reasons.
