I would make my decision based on the following
2. How wide a tire do you plan to ride? I think the Zipp has a wider internal distance between the brake tracks, so it would be better with wider tires (25 or wider)
5. Zipp probably wins the wet weather braking battle.
Not that I really prefer one over the other (except that I find the weight of the 7.8 impressive for their depth/width but a quick correction :
2. Enve website says internal width for the 7.8 is 19mm front and rear, whereas Zipp 808 NSW is 17.25mm, so it is actually the opposite, Enve have wider internal width. Not that it makes a huge difference, 15 to 17mm makes a difference, 17 to 19mm is not such a big deal anymore with a 23mm clincher tire.
5. I trust the Zipp new braking surface (as also seen on 404 firestrike) is excellent, it seems Enve also has a new brake track (same as on the 2.2 ?). I have 404 Firecrest and Enve 6.7 and both brake well so that long as new 808 and 7.8 offer an improvement to something that already work well enough to me then I don't see how I could not be happy with one or the other in term of braking ;-) .
All that being said... I'm like you guys, very interested in both but will have to make a choice. Aero comparison would we awesome but I guess it's not coming very soon :-(
