I don't know about Wisonsin but here in NY we have one management unit that has recently been made an AR unit. 3 points on a side. The DEC said that they have agreed to do this "experimentally" as the result of pressure from local hunting groups to increase the average size of bucks in the unit. Their position regarding ARwas, in a meeting I attended, that they didn't see a need for it from a management perspective but they would also consider it in other units if that's what the sportsman wanted.
