Okay, here's a question I'd like to pose to the group: at what quality level do you allow yourself (or others) to use your bourbon for mixing?

For me, my 'mixing bourbon' is Maker's Mark, because it seems to be very mixer-friendly, but straight-up it tastes like I've licked an ashtray (JMHO). That quality/price level is about where I won't cringe if somebody asks for ginger ale.
