When I took the Buffalo Trace tour a few years ago we were told Weller and Pappy had the same mash bill. I have at least one bottle of most all of the antique collection but for the money I'll take Blanton's. I don't drink my collectibles as there's plenty of stuff as good but much cheaper. I mentioned earlier in the thread Four Roses, I'm surprised no one else has mentioned it. Very good bourbon and very reasonable.
