Couple of points
1) I hope you are aware Zipp rims are fitted with oval rim washers, that need to be removed and replaced with new (non deformed) ones... it is a royal PITA
2) Sapim CX Ray is already a flimsy spoke, I would not use anything lighter... too fragile to handle and will most likely fail quite rapidly and will have lower stiffness.
3) For a bit of advice, this is my rebuild of a 303 on a Dura Ace hub, if that helps

(1) I am, I have a packet of 100 Zipp nipple washers ready and waiting to be used.
(2) Flimsy? Not in my experience. 28 spokes front and rear on my 29er MTB, and they've happily held up through crashes which have left me struggling to walk away.
(3) Yep, read it. Thanks. Seems pretty straightforward. -

if you can’t find the odd length, round up, as I did.
This contradicts the usual advice.

I'm about to start stripping down my Zipp 404 Firecrest wheel so I can replace the god-awful POS Zipp hub with a Tune Mag170. Apparently the Mag170 doesn't have the creaking issues the Mag180 did. Here's hoping.
Anyway, I'm going to build them up 2x on both DS and NDS, unlike the current setup which is 2x NDS and radial DS. On the DS I'll definitely be using CX-Rays but was considering using Super CX-Rays on the NDS. Apart from the cost of the Super spokes, and taking as read the fact that any weight saving is negligible, is there any reason why this would be a bad idea?
