Thanks for all the information.. To answer Bills' question , I'm really just trying to maximize range while keeping the quasi-single chainring up front. I believe I could achieve what I need with just getting a smaller chainring but I do find myself in the 40/12 often and I don't want to totally give up on a high gear. The advice to look at % difference between jumps in gear-inches is helpful. I'm now leaning towards a 10 speed Sunrace 11-40 and keeping all shifting pieces ..just means I'lll need to keep it friction.
I do live in a somewhat mountainous region *(I know the Catskills are more like hills to some of you*) and load my bike up pretty often ...and I also know that I can achieve what I need with a triple which I've been happy with all these years. I'm just excited to figure out a system where I have a wide low double in the front without a front-derailleur where I'm in the Middle position of a 110/74 triple crankset 90% of the time and have a wide gearing range in the back that will keep me moving *most* of the time.
