I think baco (we usually call it rum & coke here) is fine. By really strong I mean stuff like cognac. That stuff is insane.
I don't know how people can drink it. Bourbon or whiskey are probably just as bad, but I've never tried them yet.
I've tried both bourbon
and whiskey, and I DO NOT recommend them. My friend's dad gave something called "fire whiskey," and I guarantee that it is the word "awful" in liquid form. I gagged the minute it hit my tongue.

There was this girl I used to work with who would spend her weekends with a bottle of absinthe.

She would tell me, "I just kept taking shots! I wanted to see the green fairy!" Uggghhhh. I can only imagine the pukefest that took place when all was said and done. Like in Family Guy when they drink the ipecac for the last piece of pie...
