Great reviews everyone! I am glad most of you are enjoying FOS.
Brass, FOS has a real Burley character because of the Dark Fired KY Burley in it, and because of the Perique which made using Burley. The pressing melds the Burley flavor through the mixture and the Red VA Cav. takes on all the flavors and adds just a touch of natural sweetness.
Newbroom, the slivers of paper in the tin are, as you suspected, from the paper insert, which is cut by the manufacturer, in stacks. We shake the tin inserts, which we call "mouse-ears", to remove as many of the loose slivers of paper as possible, but some always seem to make it past us. I can tell you from experience, that they don't add any flavor and I usually end up with a couple of them in my pipe when I pack FOS. I have never noticed any taste in the smoke from them, but I always try to pick them out as best I can.
JMPCWJR, I agree with Brass, that for a beginner with nicotine sensitivity, less is more, and there is nothing wrong with smoking a little and then resting yourself and the pipe. That said, no blend is for everyone, and that is part of the fun of exploring, and finding your preferences. I would add that many blends that did not work for me early on in my piping, have really grown on me as I have found my stride, so don't be afraid to revisit and reassess blends over time. Maybe they will change, due to aging and maybe you will find that your tastes have changed over time, as well.
