In reply to afshapes:
From personal experience, some short routes with not much commitment to practice your steep ice technique might be:-
Alladin's Mirror Direct in Cairngorms. IV,4, has a good steep section.
Quartzvein Scoop on Beinn Udlaidh. IV,4, but requires a good freeze.
White Shark on Aonach Mor. IV,5 with a nice ice section which will allow you to practice placing screws halfway up. If that isn't formed, do Left Twin at III,4.
Patey's Route, Coire an t-Sneachda, Cairngorms. IV,5. Good steep sections with easier bits in between. I would suggest waiting for ice on the top slab.
But any 2 or 3 star IV on the Ben in good conditions will be a good stepping stone to the classic Vs. Central RH, Wendigo, White Line, Comb, Thompson's, Italian RH all have good reputations. Really, just walk-in with the guidebook and pick what looks in condition, without loaded exit slopes or a cornice.
