Are the bearings in these hubs as great as I've been hearing? I've been thinking about building some new wheels, and at first I wanted sealed bearing, 36 hole, deep rims for strength's sake. But the more I think about it the more I want fast, smooth, relatively light go-fast wheels that I probably won't ride in bad weather and that I will expect to have to maintain a bit more. My thoughts now are along the lines of 28 hole dura ace laced to cxp33's. Also, relatedly, is there any grease you guys prefer for when you repack your hubs?
