I'm actually about 205 (but I'm getting my weight down fairly quickly, riding a lot lately, and hope to get down to 190 by early summer and 180 by the end of the summer). So if these are actually too light or lacking in durability, what about an almost 5.5 lb wheelset (but cheaper than these) like this:

When I worked at a shop, we almost always had to hunt down bladed spokes for customers that broke a spoke, but I'm not opposed to buying a box if I had to, once I've settled on a wheelset. I remember Mavic being the most common so I'd think bladed spokes for Mavics would be easy to find. But I'm not a road bike expert at all (obviously) so I could be wrong. The idea of typical stainless that any shop carries in every length is appealing though.
