This is the first proposal in a very long time with the potential to balance the effects of technology and growing demand without reducing opportunity. For mule deer in particular, the opportunity to hunt mature bucks is infinitely more valuable than the opportunity to do so with the most effective weapon technology.
We don't yet know what across the board weapon technology restrictions will do to/for deer herds. There is harvest data for MZ seasons, but those generally occur at more opportune times of year to hunt. The Wasatch is somewhat of an example. It gets extreme pressure and hunter numbers but still has a good deer herd. The data coming out of these test units in 3-5 years will be very interesting.
The one exception I'd suggest would be that, similar to CO's early high country rifle hunts, some rifle tags are available at much lower numbers. That will bait a bunch of people into putting in and waiting for those instead of hunting the restricted seasons
For my part, especially for mule deer, I'd very happily give up hunting them with a scoped rifle in trade for better draw odds and more mature bucks.
