Yes, I looked at the Silk, but was a bit put off by the price premium (compared to BF's already robust---and fair---price for custom fit made-in-the-USA). I also suspect that there is a weight penalty for replacing the rear triangle with a rear fork. Being an average-to-light rider (165 lb) I would gravitate more to the lighter Crusoe frame, but then require a chain tensioner.
I did inquire for a Seattle Swift owner in my other thread (also looking for the Swift owner Ron whose fully loaded touring bike is pictured on the Xootr web site). Judging from this thread the buzz over the Swift seems to have reached a peak several years ago and been subsiding since. Feels like I'm late to the party!
Also have an inquiry in to Peter in Brooklyn, but no reply for a couple of weeks now.
