New Carbon tubulars for a new build

[skiezo]

I finally goy my new custom geo. Sarto frame and 11 speed record/chorus mix groupset. I want to build this up with some carbon tubulars as I picked up a bunch of new tubulars of various brands and widths at a yard sale for a steal. I have 8 set of tires hanging in the basement plus the one that I had before this find.
I will be riding in rolling hills with a climbing ride 3 or 4 times a month with a small group.
Anyhow, I am looking for wheels in the 35 to 45ish depth. A few that I am thinking about are as follows.

1) HED Stingers in either 3 or 4.
2) Campy Bora 2 in good pre owned condition
3) Reynolds Assault
5) Zipp 303
So far I really like the HED stingers in both 3 and 4. I have also looked a a few pair of Bora 2's. The Bora are not a wider rim like the Hed wheels are. The Reynolds Assault SLG look good on paper.
I am looking to stay in the 1350 gr. range without breaking the bank so pre owned is what I am looking at most likely.
Any other wheels that may fit the bill let me know.

Thanks Brian

Sarto + record/chorus mix = Campy Bora 2. that's your only choice actually.

The Hed rims are first-rate, the hubs are ok.
