Mavic for building. Stans for riding. I prefer the eyelets and stength of a Mavic to build, but give me the width and lighter weight of a Stans for riding. I wish Mavic would WAKE UP and build/sell wider rims (without having to buy into their wheel sets).
DT spokes used to be best to build with as they were better finished; not sure if this is still the case.
Super light spokes and alloy nipples are good for race/posing wheels IMHO. If you do this and use them hard your looking at a rebuild in 1/2/3 years… which might not be a bad thing with a Stans rim anyway.
If you want a long lasting wheelset and don’t mind the extra weight go Mavic with DT Super Comp and Brass. If you want weight weenie and are willing to rebuild a bit earlier then go with your plan.
FWIW – I ride with the lighter and wider Stans now as I like the feel. I know the rims are weaker and won’t last as long as a Mavic but I’ll live with that compromise. The next wheels I build will have carbon rims… wish me luck 😕
