I'm in favor of the ole' mature hen sound for the most part on my paddle calls.....
Part of that is being able to fall hunt, so gobblers and jake calls are very useful in a call....
The high pitched sound does have it's place in turkey calling or the turkeys wouldn't be using it in their language.
Our season has about 3-4 changes in the hen's calling, you'll hear, so you gotta be able to change w/ the sounds, your hearing & adapt your hunting style to the phase of breeding the birds are in.........
