If I was looking to mount an exceptional bird it would start and end with big spurs (1 1/4"+) which would indicate a wise old warrior. Our turkey biologist once told me the heaviest birds are often 2 year olds that have found a winter handout like birdfeeders or manure piles, and ice and snow will break beards, but spurs don't lie. The best trophy I've ever seen I guided my fishing buddy to, using my gun and camo on his first ever turkey hunt. It only weighed 16 pds and had a 10 1/2" beard but it's spurs were 1 1/2" and 1 5/8". He'd have been happy shooting a jake but it was a State Record for awhile and the biologist said it was 6 or 7 years old. Wisely, he had it mounted.
