I am a 230 pounder riding a Cannondale R600 with the 24 spoke Techno. I have ridden approximately 2000 miles. Rear wheel was trued once after a short period. Broke one rear spoke later. Today I dropped off the rear wheel to be replaced the wheel tore and one spoke is about to come out of the wheel and all the other center spokes on the sets of three have cracked the wheel where they go through. Hope you get better life than I did!
