In reply to Andy Nisbet:
Andy, as James said above. There is a real bouldery 5b move with blind feet on the first pitch (assuming it's done in two pitches, think it would be guidebook P2) above the heather ledge where you move slightly right then up.
The cracked bulge up top which you are speaking of is certainly no more than 5a. A couple of thin feet on super grippy rock (easier than Secretaries Direct, Glen Nevis) to get up to the the crack, then just one stiff pull on a super friendly hand/fist jam before you hit jugs.
The pitch would be nothing more than VS 5a in its own right if at Kilt Rock for example.
