Yep, I've ridden CYB
I'm hoping to get Betws Y Coed in again, it's a fantastic trail for flattering the rider.

CYB I wasn't hugely impressed with... Last time I rode I was rewarded with technical climbs and fire road descents. WTF?

Nope
I rode the MBR run in June 2004. IIRC there were diversions for trail maintenence.
