Probably the gray fox fight and red/grayfox fight. I have another sound that is owned by a friend and is deadly on coons. Apparently, he designed this call and he should sell it to FP or traded for a new Fury etc. The gentleman who owns this coon call is a super nice dedicated predator hunter. I'll put it this way. He had a contest against a coon hunter with a dog starting at 7pm till? Coon hunter with dog got 5 coons and he got 19 the same night. I think his call is a winner.
