Well I personally swear by vittoria randonneur's. I used them on a 1400 mile tour last summer and didn't get one flat , and continue to use them for commuting and have still never got a flat with them. They have them in 28c and 32c, (I used the 32c's on my touring bike and the 28's on my road/commuter) and are available with a reflective strip on the side for a little added safety. I will admit that they are a little hard to mount which could definitely be frustrating if you have to change a flat on the side of the road.
