There are so many variables. I think it has more to do with how much pressure the birds have than the sub-species. If you are hunting Eastern around where you live where there are moderate populations of birds and a lot of hunters and you compare that to a trip you take to the heart of Rio territory in Texas on someones ranch that is set up for turkey hunting than surely Rios will seem easier. My point is I think it is hard to compare apples to apples.
