I can put this all to rest, stop debating, it will all do the job!
Now as far as smoothnes and taste...you can't beat black bush! I am not excepting anyones retort on that matter so, save your energy!
I tend to stick to the Irish whiskey when I want something that really taste good to me, notice I implied there that it is a matter of opinion, but if I just want to be stronger than I was before, taller than i was before, and cockier than I was before, well, anything will do if the quantity is there!
