In reply to Hat Dude:
Did this in 2011 - the bottleneck was X-Ray at HS 4b (from the 2003 guide - maybe there's more than 1 "X" in the latest guide) so I set that as my maximum grade. It was quite fun but a bit knackering as it was hot that day.
I soloed them all so it didn't take all day...

Not as good quality as your list as I was going for ease, familiarity, and least distance between the routes.
Intention was then to do it again with HS 4b as the minimum grade but I never got around to doing that. Don't think I'd be soloing all of them.
