I don't have one either, but my friend does, and I tried a few different tunings on it and experimented.
The first thing you should know is that it's got rounded bearing edges, giving it a spread out and almost vintage kind of feel. It's still very deep, and sounds killer when tuned low. At medium and high, you get a bigger crack, however because of the rounded bearing edges, it's not as big as it could be (not necessarily a bad thing.)
If you're looking at big snares that still have a nice crack, you may want to go with a model that has 45 degree edges. Tama makes a load of 6 and 6.5 snares that deliver a lot of power and a lot of crack.
