At your weight, I would think that 32 spokes for the rear wheel would be the smart choice. You could go 28 on the front probably, but the rear will have already dictated the choice of rim color. A build with appropriate spoke count for your weight will be far more satisfying and trouble free than the Fulcrum 3's would be...depending on the quality of your build. Not that the fulcrums are not awesome wheels for lighter folks. The 200 lb guys that I ride with aren't just heavier, they're also stronger. That's a dangerous combination for a rear wheel with only 7 pulling spokes.
