Clydes have tons of problems breaking spokes and destroying wheels - I'm going through something similar. After much research here and over the interwebs I'm going with Deep-Vs 36 on the back. The Dyads are a close second but after seeing a bigger friend of mine (300#) run Deep Vs with 23mm tires on NYC pothole strewn streets I'm a believer - holes that knocked my mtb wheels out of true are still fine on his. Of course the build is as important as the rim/spokes.
Check out my sig, I have a two big sections on heavy duty wheels. Also you don't need the Chris King hubs - check out
this thread.
