If I had an unlimted budget for bourbon, I'd buy a few bottles of the sweet mash WR for mingling purposes. I think used judiciously in a mingling you could get a great result with it. Say, add it to the current Birthday Bourbon, or Birthday and Forester 100. If you did this and kept the sweet mash to 10%, maybe upwards of 20%, the result would be really good. I realise in effect this is what standard WR is, but mingling could produce something as good or better I think if different bourbons were used. I'd choose a base of rich sweet bourbons such as Pappy 15, ETL, Rock Hill Farms or bourbons of that type.
