Wow! I am impressed! You seem to like lightweight bikes... How could you find all those Ti bolts? If you don't mind I would comment on some details:Why don't you use a Profile Mini Mag crank? I am pretty sure it is lighter.Why didn't you use double butted spokes? With 2.0-1.8-2.0 it is not so much, but 2.0-1.5-2.0 or the KHE DT Swiss should save 30 g or more per wheel easily. I mean this is not really reasonable, but for a bike like this it would "make sense", don't you think? Have fun riding this very unique bike!
