As for farkles, what works for others might not suit you. What I'd suggest is to deal with ergonomic issues (saddle, risers, etc) to make the bike fit you...then go to the Top o' The Rockies rally in Paonia this summer and do the show and tell thing with other GS riders to put eyeballs on some of the suggestions you'll undoubtedly get. Unless, of course, you're into change for the sake of change, in which case farkle till the funds run out!
Beautiful part of the country you live in! As pretty as Vermont, but in a totally different way.
