Plus 1. I've never fully understood why this is such a neglected crag, although probably it's rather dark north facing aspect doesn't do it any favours. As you say it's got some great long climbs on it, and route finding gives it a real mountain feel.
However because route finding can be a challenge maybe it's not so ideal for a beginner, I was very inexperienced myself when my mate and I climbed Avalanche route in the early 1960s and had quite a route finding adventure.
Another great multi pitch is Amphitheatre Buttress on Craig yr Ysfa, Carnedd Llewelyn, again with a long walk in. If you climb fast, and are not held up by slower parties, you would have time on a long summer day to do Great Gully, the other easy Classic here.
