Hi,
I weigh 250 and I like speed. What worked for me was Mavic CXP33 rims.
They are like the Deep V. Incredibly strong, the only time I got the wheel out of true was when I hit big holes going real fast.
The nice thing about the CXP33 is that they aren't heavy. At 470gr they are 35 grams heavier than a Open Pro.

Match them with a good hub, and you can't go wrong.
