I've found Sterling / 1776's Sweet Briar to be a brilliant mild smoke. I also use it to cut with my aromatics that are a bit too heavy / hot smoking, and think it does a great job of not intruding on the flavor, cooling the smoke and extending the pleasure. Several of the Altadis blends I've purchased are great flavors by themselves, but even better when tempered with the Sweet Briar.
And, if you like maple syrup and peanut butter you can't beat Altadis for crazy flavors--you can make an Elvis blend (peanut butter & banana), root beer float (root beer, vanilla, cream), mint chocolate chip (mint and cocoa), or any other number of fantastical, Willy Wonka-ish creations. An ounce here and there won't break the bank either. Now if only they made a bacon flavor...
