The Pap is okay but the rock is loose towards the top - providing you're climbing it on your own, you shouldn't have any problems of people rolling boulders towards you like I had! Just don't descend the top part in front of anyone!
As well as the Munros, there's quite a few easy Corbetts in Glencoe - Beinn a' Chrulaiste is very straight forward - it's the one opposite Buachaille Etive Mor - across the road... There's also quite a few Corbett-sized hills go from the top of the Devil's Staircase (at Altnafeadh) and towards the Aonach Eagach - I did that once with my friend (he went on the first part of the Aonach Eagach ridge - I just wanted to have a look out of curiousity). It is very easy and straightforward all the way to Am Bodach and then you can either descend back down the corrie before that and walk back up the road (or Gen. Wade's road - the boggy, grassy one parallel to it), or just reverse your route (not boring).
There's also an easy Corbett next to Sgorr na h'Ulaidh - think it's called Meall Ligiche or suchlike. Sgorr na h'Ulaidh itself was easy too...
Hope you find something nice - have fun... and welcome to the site!
