In reply to Landy_Dom:
Tryfan Bach definitely had ledges on some routes. Otherwise Rowan or Pulpit routes on Milestone Buttress are easy and comfortable.
Cneifion Arete is pretty straightforward but the walk in is a bit longer. It's one pitch of Diff then scrambling that can be roped.
Moelwyns are supposed to be good but haven't been yet myself. Not sure if there's much there below VDiff.
There's a route at Tremadog which is very easy and two pitches, maybe Boo Boo?
