In reply to Matadoors:
There are quite a few on Lliwedd. Horned Crag, Central Chimney, Slanting Buttress. If you do Avalanche/Red Wall your second needs to be happy about traverses, as the crux is the traverse. However, the hard step right is well protected by something like a Friend 2.
Slanting Buttress is probably the best to start on, as provided you actually find the correct buttress (not that hard), it's all on big positive holds with almost no route finding problems.
