I've got a few friends that have the buck roar by primos. I actually like the tone on the call. It is very versitlie. I wasen't however a huge fan of the fex tone calls. They didn't sound right just MO. I use my first grunt call. It is a varible Halley Caller Tube. Can't even find their stuff anymore. I even cut the reed a lil more and can great make some great calls.
I use an all wood call made by Mark Rainbolt. It's just like the call pictured but in Walnut. I had Mark make me mine for IL as well and I had good results with it. The call is adjustable by sliding the "O" ring to the desired sound. It adjusts from fawn bleat to mature buck.
Mark can make them out of just about any wood you like.
The other call in the pic is tube call for turkey.
Light travels faster than sound. That's why some people appear bright until you hear them speak.
