Question re Mavic Hubs

[Supafly46]

Hi, not sure this is the right spot to post this, but here goes.

Looking at putting together a custom wheelset using a set of ksyrium SL hubs that i have spare. So question is, will I be able to do this using something like Sapim spokes and Carbon 50mm rims from a Chinese supplier?

Its going to cost me nearly the same as buying a Yishun set of 50mm so the next question is _ worth doing on those hubs vs Novatech or whatever brand hub they ship with? I already have a set of SLs and find they ride very nice, so assume shouldnt be very different on carbon rims.

Thanks
