I ultimately decided against using a decanter, since they don't really do anything for bourbons, but when I was looking into getting one, I decided on this one.
I happen to really like Libby glasses, because I've had a few of their Gibraltar series growing up, and they've survived about every nasty thing I've done to them, including drops from greater than counter height on more than one occasion. Plus, I tend to hate things that are overly ornate, and prefer simple lines with less ornamentation, which I feel like this one mostly delivers on. Plus, that one's dirt cheap, comparatively speaking.
