Its a cracking walk, Blighter (for some strange reason, i always want to add the words "yer little" before your name)
Last time we did this - about six or seven years ago, my poor dog could barely walk the next day due to sore paws - so much we had to cancel a walk up Harter Fell and go shopping in Keswick instead.
Before you go, though, check out Wasdale mrt's website as it has some information on the routes between Scafell and Scafell Pike. Apparently - the Lords Rake route has a long standing (or long slipping!) problem with a very large and unstable boulder, and the Fox's Tarn route has recently had some quite big landslips. One of the reports about this is a bit hairy to say the least.
Broad Stand is, of course, not recommended for yer average walker who prefers to live a long and happy life. I dont think there is another route which doesnt involve a long descent.
Anyway - its worth checking out those routes as the situation seems to change from time to time.
