"A half step triple would work, like a 44/40/28 for example. The numbers are off the top of my head, not a suggestion. Having the half step would help split some of the large jumps in the cassette."
You guessed pretty well. The jumps in the 13-42 average about 18%, and a 44-40 is about a 9% change, so that's a near perfect half step. A 28-42 is a pretty low gear, so if anyone really wanted to live through the glory years of half-step gearing again, the 13-42 would work. I don't know why anyone would want to shift so much if they didn't have to, but you could.
