:withstupid: I agree. It also depends on personal preference. For instance, I personally like a call with a consticted straight bore mouth piece. I think that it give you a lot more control and a lot more speed. I think that a call with a smaller mouth piece is also more comfortable to blow.
Having said that, there aren't a ton of calls like that out there. The Super Mag Pro from Grounds is one I really like. The Foiles Market hunter is ok. I also really like the Little Man from Zink. I personally use a Michigander from Lewis Custom Calls. Whatever you choose, just remember that high pitch generally kills more geese.
If you want more info on the Michigander you can PM me.
I also have a wooden Super Mag Pro for sale.
