Mike,
The one thing I've found wrong with audio of turkeys is the simple fact, that it's a muiltitude of turkey talk....Having so many turkeys talking at one time, makes it very difficult to isolate one hen for practicing your calling. Hearing them is great, but not very good for practicing ....
I'm in favor of the talking of spring hens. Especially the soft talk..IE: the walking yelp,& purrs and clucks....Cutting would be another item of interest for me.... fly downs, too....One can never hear enough QUALITY turkey talk....
On a side note, I be glad to buy some footage of anything fall related in turkey talk.......Kee-kee's kee-kee runs and so forth....
