Definitely a tough route. If you ever are on the Ward Brook Truck trail climbing the Sewards, be sure to stop over at Duck Hole. Gorgeous place. The leantos at Camp #4 have been rehabbed, that was a tough weekend bringing up tools and supplies (and then back). BTW, I didn't see you list a bear canister on your gear list, just a note: they are required in the Eastern High Peaks Region.
