Any Scotch drinkers?

I've been a big fan of good ol' Jack on the rocks for quite some time but recently got turned on to Scotch. I tried a Glenfiddich 18 yr single malt (neat) and loved it. A place here had Johnnie Walker green label on sale so I bought a bottle of it tonight and man is it smooth (with a little bit of ice). I'd like to try another single malt though - been looking at Balvenie 12 yr for the next bottle.

Any recommendations? What's your favorite Scotch?
