I just received from them a pair of novatec/pillar bladed spokes/A29C25D22(standard version).
I think build quality is good, nothing went wrong after first ride.
Price is pretty good, communication too.
About the rim A29C25D22, they do the job i was expecting. Compared to crest mk3, they have approximately the same weight so acceleration is similar but they seem more responsive when you put high power. Ride is a bit more rigid and precise but my fear of having something to harsh is away
nevertheless you can't rely too much on front wheel flex to save you from wrong line choice like you do with aluminium rim.
