I have the same dilemna as you, I ended up choosing Lower Manitou Lake this year. From the lakes I have fished, I would highly reccomend Canyon lake which is right by Eagle Lake. It is loaded with muskies, in fact they are right off your dock. I brought guys up there who had never fished in their lives hardly and they caught a few. I personally only caught 4 in a week, but I raised a ton, and I was just learning the Lake and also a beginner Musky fisherman at the time. I know if i went back i could hammer them. The only thing i didn't like was the lack of any pike fishing for those down periods of time during a day. I also fished Cliff Lake, where I have seen many large ski's. They have some smaller lakes connected to it that you can portage into via a creek, last year I caught 6 in one day, though the size was nothing bigger then Mid 30's it was a blast.
