UncleNorby covered the age and size pretty well! I think any bird you call and shoot yourself is a good one. I've been lucky enough to take some very large birds, but I've been just as proud of a smaller Toms. Its sometimes is just the hunt that makes them good birds! How much they gobble, if you've been on him several times and finally sealed the deal, or finding a strut zone and waiting out one of those ole tight lipped toms usually makes the bird for me!
