You won't necessarily be disappointed, as a lot of times, the "hand picked" casks offered by folks such as Binny's, Sam's, etc., are better than what you might usually get. It's like what I've referred to when I've noted a particular bottle or two or Baker's that I had recently as being above the norm, or when I ran across a bottle of Booker's two or so years ago, that I was so thrilled with I put up a post here all about that bottle.
What you are trusting when buying from a merchant such as Binny's, is that you will agree with their tasters that the bourbon is exceptional compared to the usual bottling of that label. You may or may not agree. I do have to say this about Binny's though. I find that the little reviews under a lot of their product listings are right on.
Binny's has built a tremendous whiskey selection over the past two or three years based on the influx of some new talent in that department. I would venture to say that the people who do the tasting and selecting of special barrels at Binny's are most trustworthy. You really can't go wrong taking a chance on the two you named, since they are not really expensive bourbons. I'd love to hear what you thought of them.
