WOW !! Rough crowd !!
I bought a Flextone pro-pack about this time last year. It was on some deep clearance at Midway. I thought "what the heck" ?? Bought a Quaker Boy 3-pack at the same time.
After running all the calls, the Flextone calls were definitely better than the QB's. Ran the Flextone's last spring and a number of dead toms thought they sounded, at least, OK.
I don't get into (nor do I know) the politics of turkey calls and who I should or shouldn't like because he is on TV. I just know that the 3 Flextone diaphragms I got on clearance weren't crap, junk or garbage. They are sleeping in my fridge right now, waiting to be cut loose again.
