I think you'll love Nightcap ... eventually. I'd start out with a small quantity of something milder. You can always move up in strength, but why not take it easy at first, with either Dunhill's Early Morning Blend, or if you want something special for an introduction, Nat Sherman's 536, mild but really delightful complex flavor, a real treat. Keep your quantities small with tins or bulk tobacco, even when you think you've found something terrific. As a new pipe smoker, you want to try around quite a bit. I'd give it several years before buying anything in much more than 2 ounce quantity, even if it's your current favorite. After trying a mild English or two, you can branch out into the Virginias and Virginia/Periques, and some of the incredible burley blends from Cornell & Diehl and others (start mild again, I'd suggest). Take your time, and take it easy.
