You want light wheels? Get tubulars. Even a 36 spoke tubular wheel built on a decent vintage competition quality rim will be lighter than a low spoke count wheel using a modern aero clincher rim, and stronger as well. People complain about the "fragility" of tubulars. My experience (over 30 years now) is that (given decent roads) rider weight is the biggest factor affecting tubular tire longevity. Under 70kg, no problems. More than that and negative issues proportionately increase with rider mass. That's why I try and stay under 68kg.
