I guess that's what I'm getting myself for Christmas then. We found three bottles of the 141.2 proof version at the store down the street. From what I can tell in my brief research, this is the 2003 version. The idea of uncut and unfiltered is almost romantic. This sounds like it will be a nice bottle to have around for special occasions.
Yes.. go with the GTS, particularly if you haven't had the opportunity to try it.
This spirit has taken on almost mythical proportions amongst whiskey (and particularly boubon) drinkers. My reacion is that it ranges from great (the earlier, pre 2005 versions) to very good (the Spring and Fall 2005 versions.)
Since these are very high proof bourbons, I recommend that you try them both straight and diluted with water to about 90-100 proof to get a full appreciation of a very nice pour.
