Lost most of my confidence after a crash in the mid-90s. Was heading down a rocky track trying to keep up with someone that had talent and realised I was in that no-mans-land of going too fast to control (for me) but not having ability to slow down safely. Choice was crash into wall to left of me or head off side of hill to right of me. Next thing I remember, someone had chosen the former and I was sat there with both wheels trashed, Pace fleece trashed, looking at my helmet that was a very sorry state wondering what might have been. Not injured, but scarred all the same.
Still way too nervy going downhill now, but discs and FS help a bit!
