Man, I wish I was free to take his spot!  That's a great route that I've wanted to revisit for years.  However, I'll be in the BW at that time.

Well I certainly hope your friend will be able to go.  It's a tough route, but should be doable for your friend.  As I recall, there's a significant elevation gain & loss from Kashapiwi to Joyce.  The rangers did build a fire tower on that same ridge for good reason.  You won't be travelling on well worn portages, that's for sure.
