In reply to alexgoodey: March is often the best ski touring of the year, but its possible there will be very little snow (its Scotland not the Alps).
Most of the ridges are not particularly rocky, you don't say which map you have, but I suspect your just looking at the legal rights of way rather than all the paths, plus for most of the terrain, you can wander almost everywhere (cliffs & lakes excepted). In fact, if you want scambling you'll probably have to plan your route to make sure you find it, obvious scambles to include would be NE Ridge of Angels peak (Sgor an Lochain Uaine) & the Fiacaill Coire an t-Sneachda
