I don't think it's a "hillbilly" image problem so much as the giant marketing machine behind JD. The masses buy into the marketing, while those who really know look for George instead.
I haven't bought any JD since... well, when I was underage. Although, based on the taste of Silver Select that I had (thanks Chuck!), I'd at least consider getting some JD Single Barrel.
As for long-necked bottles, I like them - and that beautiful Saz Jr. bottle has an even longer neck than GD #12.
