Lightweight with a capital L is a well known very high end brand with integral carbon spokes. They feel like nothing else.
In terms of performance, light wheels are very responsive but don't hold speed as well. They're useful up hill but of 0 benefit on the flats. Aero wheels (think 30-50mm, whether alloy like Boyd's or carbon) on the other hand do provide a benefit. But if you're not racing or trying to hang on to a group,does it matter? I have tons of go fast stuff but its mostly pointless now as I've given up on groups due to the inability of most to ride like cyclists as opposed to aggro beginners.
