Although the jury is still out on regional genetic traits of deer, I wouldn't put much stock in the idea that deer from one area are bigger/better than deer from another area based on where the two areas were stocked from. As we learn more about the genetics of deer, I believe we will find that differences in genetics that produce significant differences in biology between areas stocked from different sources do not exist. In essence, Natural Selection, which can work much faster than most realize, washes out non-native genetics pretty quickly.
