In reply to RedTar:
Scrambly ridge walks:
CMD Arete
Beinn Fhada ridge to Stob Coire Sgreamhach (short section of I) /Bidean/SCnanL.
Beinn Bheithir (E ridge of Sgurr Ban has short sections of I)
Stob Ban N ridge (short section of I)
Devil's Ridge, Sgurr a' Mhaim (longer section of I, full Ring of Steall has another section of I)
Easier mixed climbs (Grade I/II):
E ridge of Beinn a' Chaorainn
Ledge Route, Ben Nevis
E ridge of Carn Dearg Mheadonach
Dorsal Arete
Sron na Lairig
Golden Oldy (you maybe did this with your instructor)
Easy gullies:
Central Gully on Bidean (I or II depending on the choice of route)
Broad Gully (I), Boomerang (I/II) and NC (I/II) on SCnanL.
Central Gully (I/II) on Creise
South Gully (I) on Stob Ban.
Tower and No.s 2, 3, 5 on the Ben.
A 30m rope is OK for the easier stuff, but it will start to be a pain if you want to pitch most of a route.
