My IF serial number also appears not to relate to size. There don't seem to be a lot of IndyFabs around these parts, not like New England or NY (duh, of course there'd be more closer to IF’s hq). The ones I’ve seen here are pretty evenly split between ti and steel, but all the owners seem to love them. What I’ve read here seems to bear that out!

IFj, I do have way more bikes than I should but swear that I use each for a different purpose (also DH is an eBay junkie). Frank the Moser is my rain bike and currently stays at a friend’s work where a group of us suffer twice a week under Evil Coach Troy. Barbie, the old Merckx, is my winter bike - I ride shorter distances and slower in winter so figure I get a better workout on a heavier bike. Fred the Fondriest is the light "fast bike" that I use on hard training rides and most centuries during the season. PeeWee with his couplers and compact crank is the "do it all" bike, though, and may end up replacing Fred as well as Blanche, 'cause even though PW's a little heavier, he just fits and rides so well. I used to ride off road a lot on my mtb but for same reasons you cite, don't do really technical singletrack anymore - hurts my knees, one of which is overdue for scoping anyway. Must work on that flexibility in the meantime. Riding a road bike can still make us feel like kids, right? Go Godiva!
