Well, this would be good for starters:

Even if the actual six pack isn't available anymore, you could assemble a mixed 6er of all but the Odell Red. Which I guess would make it a mixed 5er...
Woodcut, Bourbon Barrel Stout, and Saboteur from Odell Brewing (Fort Collins) would all be worth a look. All come in 750 ml bottles and are a bit pricey but delicious. Odells Cutthroat Porter is one of my favorites, particularly served on nitro.
Old Chub Scottish ale and Ten Fidy imperial stout from Oskar Blues (Lyons and Longmont) both come in cans and are great for colder weather. But OB might distribute in Wisconsin now, I'm not sure.
Fort Collins Brewery makes a great Chocolate Stout, and if there are any bombers of Double Chocolate Stout left in the liquor stores (I think it's seasonal), those are particularly decadent. You might like the Z lager, too, which is a Rauchbier.
Sounds like you prefer the maltier beers, but if you happen to like Saison, Funkwerks brewery in Fort Collins is making a really nice one these days.
