I’m 100KG+ and have ridden 355 rims on Pro 2 hubs for around 4 years.
On my FS and whilst I don’t jump silly, I like to rattle along trail centres and the peaks etc.
Mine never put a foot wrong and have not been touched since buying from Wheelpro, until recently when the 2nd trip down the extreme DH course that is Sherwood ( lol ) resulted in the front wheel snapping.
Can’t remember if it was cause or effect, but I have now replaced the wheels with a set of Arch Ex from 18bikes. 🙂
If built properly the Crest will be fine for you I suspect.
