In reply to puppythedog:
If she's a novice, Flying Buttress would be better than Wrinkle. Last time I did Wrinkle I had a novice belayer who, due to the nature of the protection there (weighted slings over spikes for one succession of placements IIRC) kept me on too tight a belay and all my runners lifted on that section. Fortunately I was happy with the climbing, but I effectively soloed that pitch.
FB, OTOH, is a classic route. It gets into a nice airy situation with very obvious route-finding, loads of bomber protection and initial pitches that aren't at all intimidating. The belay stance after the rising traverse is great for giving a novice good views and a taste of exposure in a well-protected setting. It might be crowded, but last time I was in Wales I was astounded that, even though the weather was fantastic for the whole weekend, we saw no-one on the Cromlech and only one other pair on the Milestone when we moved over there.
Milestone Buttress Direct's a nice route too, but the final chimney can be a bit of a thrutch and a novice might really hate it...you can bail there though....we saw a fair bit of abseil tat over at the side of the last stance before the top so obviously several parties have given up at that point recently.
Another thing is that the descent of FB is very straightforward and a novice won't have a problem with it. The usual descent from the top of MBD can be a bit intimidating for someone not used to a bit of exposure....the last bit before the scree gully is an easy down scramble, but the first bit of the descent is on quite steep ground above a fair drop, though with very positive and large holds for both hands and feet.
Personally, with a novice, I'd do FB first.
