I'm like you, I used to drink mostly tequila, or as I like to call it "The breakfast of champions!"
Anywho, then I started with Irish whiskey because I heard it was smoother and I liked it, so moved to a couple of blended Scotchs. Now I'm entering the world of single malts, and finding it quite enjoyable. I have found that I like the ones with strong, intense (to me anyway) flavors, but haven't had the chance to try anything in the Laphroig class yet.
Thanks to Beuth Sim, I did get to enjoy some Glenkinchie thought. Very nice.

I'm still not much of a burbon drinker though. And I try to steer clear of moonshine as much as possible.
