If your not going to uplift you might as well give Lee Quarry a try that is probably one of the closest places with trail centre type trails.
As for Uplifts I find Antur Stiniog is very approachable, I’m not great but can get down all the tracks there from the Blue to both Blacks although I always give the big drop off a miss.
It is unforgiving if you crash there though and any bad weather (wind and rain) can make it very difficult.
It is not that hard to get down the trails but the skill needed do them fast and to clear the jumps is on another level altogether!!
Which makes it suitable for most skill levels from near Beginners like me to the Pros.
I’ve not been to Revs but have been told there are some trails there that I wouldn’t even be able to get down at all and it’s even harder when very wet.
