You will have a great time at Eddie's. I have never been to his camp,but have fished in that area with Northern Outposts at several different lakes.
I'm going to the Pickle Lake Area this year,I'm not sure yet,but maybe to North Caribou Lake. Went there in 2007 and caught a Ton of fish Have a great time planning your trip,and post a report with pictures when you get back
