So I'm planning on renting a couple pairs of Zipps this summer for a planned purchase in the fall... Finishing residency and getting my first real paycheck has its perks. I'm looking to buy a pair of non-disc wheels so I'm covered for the no-disc events, and then adding a Sub9 or 900 disc later on.
I'm a pretty big dude, weighing in at 215 right now but hoping to hit 200 by season's end. I'm reasonably fast on the bike but not a beast. The two wheelsets I'm looking at are the Zipp 808 Clydesdale tubular and the 1080 tubular. As for recommended rider weight, Zipp says the 1080's are good up to 225 and the 808 Clydes are to 275. They also say that above 190lbs to "consider the 404 or 808 Clydesdale."
I guess there's really no way I'm going to answer this question without riding both sets, but demo-ing 808's and 1080's isn't exactly easy or cheap. As for behavior in crosswinds I think it's kind of a wash--I'm big enough that I could probably run a front disc and be ok.
What I can't seem to answer is the difference in lateral stiffness between an 808 clyde and a 1080. Anyone have any experience with these two wheels and care to comment?
