In reply to ClareM.123:
We did this a couple of weeks ago. Although you've got a lot more height gain to do on the walk in (going over the saddle) I recon the path is much better (less boggy) and the walk out was definitely quicker (we'd done the ridge scramble on the other side the day before and walked out down Glen Rosa).
We ended up ditching our bags and racking up at the saddle and then following the contoured climbers path (obvious once you've found it) to the base of the slabs. This also means when you finish the route you can head up over the top and down the ridge to the saddle, which is a nice easy walk off, with some great views. Watch out for the deer, we came across a couple of large groups which were friendly enough, but they blend in pretty well.
Let me know if you're after any beta
(we did the former of the two options above, seemed more direct to us)
