Pike. Want some? Come on out to my dad's place and you can have as many 20" NP's as you can catch.
Seriously, though, taking advantage of a northern location, as much as they are being a problem for me at the moment, you could have some awesome pike fishing in there. But personally, I love pike, my dad hates them, and i think i get the same 50/50 sense on these forums.
Maybe Tiger Musky would be best though, sterile as they are, then you could really monitor how many you had at any given time.
