I don't think that it would be very feasible to expect most hunters, especially young hunters, to be able to determine the age of a deer on the hoof much less the circumference of the antler base. What happens if someone with a "mature buck tag" shoots a buck that doesn't meet these requirements? In my opinion, it's too confusing.
That is why they have a choice in the type of tag that is purchased, if they do not want to be restricted on the type of buck they shoot, then they pay for the 'non-restricted' tag. If they choose to be a part of the improvement efforts for deer hunting in OK, then they can purchase the mature buck tag and follow the harvest guidelines. If they shoot a deer that does not meet the guidelines, then they can pay the difference between the tag value at the check station...not a fine or violation, just making up the difference.
This is really not that complicated, especially compared to some regulations that are already in place.
