Well, I can' t argue with that. I think spread would be a great metric, it' s used in DE with no complaints, at least none I' m aware of. I would say I doubt all those 2.5yr old bucks will get shot, they' re a year smarter, remember. And radio collar studies show the older a buck gets, the fewer of them out of a given number will get killed by hunters. Even on heavily hunted property, most studies show that at a certain age, depending on what part of the country, the least of a buck' s worries is hunters. DE hunters had no problem with spread being used, but you would know better than I how difficult that would be to institute in PA.
