The weight "issue" is a non-issue. I REALLY like light bikes - but just in the same way that I REALLY like Italian sportscars. They're nice to have, nice to show off, nice to fuss over. But they don't get you to where you're going in town any faster than an '86 Hyundai Excel!
According to Jamis that bike weighs 26 lbs. Do the math with your own numbers, but for example if you weigh 180lbs and all your gear - your fenders, rack, bag(s), lights, change of clothes, lunch, water bottles etc. etc. - weighs 25lbs (a conservative estimate - mine weighs a LOT more than that I'm certain) that bike will add a whopping 2.6% more to the overall package versus a bike that started out at 19 lbs. You'll notice ZERO difference. If you're putting a stopwatch on your ride every day and getting long-term averages you might be able to pick out the fact that you're a few seconds - perhaps an entire minute - slower.
As far as the cross levers go - as previously mentioned, add them. Do you really ride bikes that are precisely as they came from the factory? I've never had a bike that I didn't modify in some way before it left the store and every one of them has become more and more of a "frankenstien" as time went on.
