I 100% agree with Hank. I was up on BS a few weeks back and decided that although I think I'd be happy to do it in good conditions, it would be a different story in potentially wet and claggy weather and there's also the tiredness factor - to say nothing of how your pacers feel about it. It will be LR and WWT for me with Foxes Tarn as a back-up route.
I did a Leg 3 support earlier this year and the route employed was what I think is called "Foxes Traverse" or "Climbers Traverse", where you drop down towards Eskdale as normal for the FT route, however you hug the bluff and get onto an outcrop/shoulder that means you don't have to lose as much height and join the gully much higher up. It's OK in dry conditions (it was), but could be a bit dodgy if wet or you don't have a head for heights.
