In reply to AB:
We did the traverse last year, and Bidean wasn't nearly as tricky as reputed I thought. Admittedly, we had good visibility. The abs were all obvious imo, though a certain amount of faith is needed in going along the roof-like bit on the first ab, especially if you couldn't see it. Mike Lates' descriptions were spot-on as usual,
If I recall, the last ab needed some care as it went over a bit of an edge, but it just needed some thought.
I think the fabulous thing about the Traverse is that it's a constant adventure of exploration, and nothing is ever quite how you imagine. For example, the downclimb to the chockstone on Bidean focused us (!), and that bloody jump on An Casteil spooks me every time!
If you are confident in big mountain terrain, just go for it, and enjoy some of the most absorbing scramble cum mountaineering you'll ever do
