In reply to aldo56:
option 1.
If the forecast is that good, and possibly good conditions underfoot set the alarm earlier, and make sure the headtorch has good batteries in it. it will be WELL worth it.
option 2. choose from below.
Round of Coire Ghaothach on Ben Lui, up left hand ridge and down right hand side, (grade 0.5).
East Ridge of Stob Bhan (Beinn a Bheither) above Ballachulish. (grade 1ish)
Or Sron na Lairig in Glencoe (grade II), with descent along the Beinn Fhada ridge.
Curved Ridge in Glencoe (II/III).
Aonach Eagach (II/III). May require an early start also.
option 3.
pick any other hill, follow your nose and find an interesting way up it.
