Steve, I like your Century Special 13-30 range. That may be something for me to aspire to. I'm not really sure of what I need for a low gear. I like the idea of the 18 given my currently weakened state. As I build strength and endurance, a higher low gear that allows closer spacing may be preferred. I guess I'll know when I get there. :)
On to some great news: Now that I've selected the 3x9 with bar ends that Riv stocks, my build should be done today and ship around Tuesday of next week. Yeah! :D Thanks again everyone for the continued education.
