The split between mule deer general and w-tail general is where the reduction in crowding is going to be the most significant. If I choose a w-tail only tag, I'm not going to be over hunting the Custer for mule deer...and vice-versa. Plus, that will save a mule deer from me shooting one, since I don't have a tag valid for mule deer to begin with.
I'm not seeing how adding a shit-load of days to archery is going to sweeten the pot...very few archery hunters in Montana are archery only guys. They're 2 season hunters that will drop the bow in the trash if they have to choose one or the other, more days won't change that.
No different than if you had a "traditional only muzzleloader tag"...very few would choose the December only season no matter how long it was.
Finally, if we truly care about the resource and giving them a break from all hunting...archery, rifle, muzzleloader, then stacking more days to pacify archery hunters makes NO sense.
The animals need a break, from all weapon types. If 30 days isn't enough, then go shoot coyotes, ducks, pheasants, etc. or go fishing.
