If you were not using a disc, which pair of deep sections would you choose:
808’s
Stinger 9’s
DA C75
Mavic Carbone 80’s
Kind of interested more in the DA wheels. Like the looks, and the hubs…
Zipp 808’s for clinchers
Stinger 90’s for tubulars
.
Aeolus 9 rear , Aeolus 7 front
.
Hubs can be an important consideration as it pertains to durability or serviceability, but among wheels of that quality there will be no difference in how fast they make the wheels go.
Are you decided on tubulars for sure already? For triathlon and time trial purposes clinchers can often be a faster solution when tire choice, and spare kit are all taken into consideration, even on hilly races.
If you are stuck on tubulars, the 808, stinger9 and Mavic Carbone are all excellent choices, but I would not use the Mavic tire. Despite the custom aero shape, the CRR is bad enough to make it not the best choice overall.

Any thoughts on the DA’s?
Aeolus 9 rear , Aeolus 7 front
+1. (Tub or clincher) clincher for me.

From pictures of them, and their marketing claims, they seem to have gone with a similar shape as the HEDs/Zipps, but I just don’t know for sure how well they do aerodynamically.
Anyone seen some aero data on them?
EDIT: from my own damn website, I found this link:
http://www.aeroweenie.com/assets/img/data/tour-wheels.jpg
I wonder if that is the previous verion of the C75 though, I’ll try to find out.
Ok I found the whole Tour article, and yeah it was the latest Dura Ace wheel, so looks like it isn’t the greatest.

On that chart, I belive ‘Scheibe’ means disc?
If yes, then it looks like at 35km/hr (just shy of my 70.3 average… 
), there is a diff of about 2.5 watts between the C75 and the 808?
Clincher vs tubie…I’ve been using tubies for 20 years. I like the idea of clinchers, and I think the nicer clinchers ride pretty much just as nice as quality tubulars, and I believe the rolling resistance data that shows good quality clinchers may be faster…but in all my experience, both my own, and many other cyclists I’ve known, there are far less flat tires with tubulars. Whether it is because they are less prone to pinch flats, or because they roll over objects better, I dunno, but that is my experience…and I hate flat tires!!! On tubies, I’ve averaged about one flat every two years. So for me, I choose the reliability over the rolling resistance. I do make a point of riding good quality tubies though, usually either veloflex, or top end vittoria.
Cheers
I believe clinchers flat more due to installation errors that are impossible with tubulars and the fact that clincher tire owners don’t often replace the tire after it flats! So they can be avoided, but it takes a lot of care to do so. On the other hand it takes a lot of picking at glue to deal with tubies =)
Not a big deal either way, and at least you end up with less weight with tubies.
So yeah, about 2.5 watts between the two wheels. Not a ton, but I’d rather have them than not have them!

Tom A roller tested the new Shuable tubulars and the Crr was a 31. The also have textured sidewalls for an aero advantage. I don’t know how aero they are, but they have nearly as low a Crr as the Vitorias and are probably more aero.
I anxiously await some sort of aero data on them! Can’t be as bad as the Vittoria’s surely
