I'm no fisheries biologist, but I have swam in a lot of muskie/pike/tiger rich lakes in Minnesota, Wisconsin, and Ontario. Still have all of my toes, and I've never heard of a member of the Esox family attacking anyone. They are ambush predators of fish. Large animals are not a food source to them. If you don't have anybody who wants to fish for them though, they might end up consuming biomass without adding fun.
300k for a 2000 acre place with a 125 acre lake... that seems like a hell of a deal. You saved a lot there, I really would consider getting out an expert to help you stock. I mean, you're probably looking at $1,500 worth of LMB alone by my back of the envelope calculation. You'll save money in the long haul through being able to develop a better stocking/management program for your lake. Also, a biologist might be able to give advice on how to make your lake better for hunting, perhaps by adding duck/deer/dove friendly habitat around the shores.
