Every time I read "BV" in someone's post I initially translate it as "Bike Village" then have to stop myself and reparse it as "Bike Verbier".
Thanks for the continued advice. Really, comments like:
I reckon trails in Verbier are equally as challenging as trails in Luchon. True there is more uplift in Verbier although I prefer the challenge of a climb to earn a descent with AQR.
Are at the core of what I've been after. I've been to AQR (really, it was in the OP, I don't need recommendations about it ) and I know how I reacted to the difficulty level of the trails and the riding there, so the above helps me judge whether I'd do OK at Bike Verbier.
I [...] don't think Phil and Lucy would take you down something crazy if you were a novice!
Not a novice, just not always very good! Plus with an annoying ability to get properly dispirited if I'm worn out and I start encountering too many bits that are just a bit too hard for my confidence/ability.
