Well I just have to post a follow up. I had ordered the Vittoria Randonneur Hyper's online after an unsuccessful search of the lBSs and have been riding on them for about a month.

OMG. They are 35c like the regular Randos the bike came with, but they were 300gr less weight each. And they are wider. They look more like 40c. The ride quality is excellent. I've been running them pumped to 85 and they really roll smoothly and help with the chatter over our crappy roads. These are impressive tires. In back, I used a slime-light tube; they are not very heavy and can help seal the goatheads I always seem to get stuck in the tires.

Losing 1.3 lbs with just a tire swap and having them turn out to be really good riding tires without breaking the bank is a home-run!
