Oh hell, raspy, squealin", mellow...don't much matter, these are just tools of the marketing people to keep you buying calls! If you are in the right place any of them will work! In reality, if you are around a tom that is "hot" he'll come a running, if he's busy with some hens, he won't. Get a couple calls, learn to use them "appropriately" and they'll work. Or, hell, be like me a buy a bunch of calls...lot more fun.
