Jmo but if I was buying a friction call right now there is zero doubt in my mind when I say the first phone call I'd make is to Darrin Dawkins and get an aluminum call from him.
I'm as particular and peculiar about what call I carry and there is not a better call on the market for killing turkeys. Period IMO
This over that, that over this, fancy wood, fancy etching, funky pot, etc etc are things call makers do to lure hunters. The really really great call makers, make simple calls and put all of their time into perfecting each and every call that comes out of their shop. I have half a dozen Dawkins friction calls and every one is identical in sound. IMO that is the true mark of a great call.
If you want a call that looks cool, is made of 1000 year old wood, comes with a snazzy striker etc etc then that's your business and more power to you. But if you want a call that matches a turkeys sound perfectly and is made to murder birds then look up Darrin, he only makes about 100 calls a year so act fast if you're interested
