In reply to damomcgovern:
Done Agags twice and NF about four times, both most recently in last two years.
NF harder than Agags but also better in some respects. On Agags all the climbing difficulty is concentrated in a very short section at the crux (although I suppose pitch one has tricky climbing too but doesn't feel so committed).
On NF Route there are several sections of difficulty, a couple of which may feel quite bold and one strenuous (I'm deliberately not wanting to be too specific and spoil it for you) but NF route never feels as exposed as it looks in places.
On Agags there is little value hauling up your rucksack as descent is short and reasonably straightforward back to the base of the route, . On NF Route I think it makes sense to carry the sacks up and over the summit as the descent is so long. You may be able to descend Heather ledge back to the traverse pitch but it's 30 years since I'd have done this and you'll have to do your own research or be advised by a more recent visitor.
I'd also finish over Stob Dearg from Agags as I don't enjoy the descent of the lower bit of CR any more.
