I know that feeling. $50 is a lot to drop on something to give it a shot.....so is $30.
If youve had and like Dickel 12, Id suggest going for it. If you dont care for D12, you might wanna pass and see if any restaurants/bars have any first so you can try it out.
I liken it to the differences between KC and KCSB....strong family resemblance, but enough difference to matter.
