As you can probably tell from many of the responses, the Therma Rest Neo Air is the way to go. After screwing around with other pads trying to save a buck, i bought the Neo Air I should have purchased the first time. I spent far more money in the process. Bring a patch kit and you will be fine. The closed cell pads are fine for adding insulation on cold trips, but they don't pack well on a bike. A lot of people strap them to the top of their rear rack between their paniers, but that is about the only place they fit. If you are using frame bags, forget about it.
