Try Mattice Lake Outfitters. I have a hunt booked with them for my wife and myself for 2013 (baby coming this fall so we have to wait). They have several fly in options to cabins and tent camps. There is a fellow out of Wisconsin that took his wife last fall and they both got bulls...Hers was bigger, of course! Very reasonable $$, decent success rate from the research I have done; that is why I booked there.
