Derekflint,
Sir John's is my #1 VA flake right now and has been for the last ten to twelve months.
Nearly a year ago, I was looking for something new. I'd guess, like yourself, I was looking for something new and conducted a detailed search on "TobaccoReviews.com"; noticing the high ratings. I purchased two tins and after the first two or three pipe-fulls, directly purchased several more tins.
It's a great flake tobacco and I encourage you to try it if you like VA flake. Good from the tin when arrived, better, given a bit of age. Personally, I like it more than Full Virginia Flake and even Dunhill Flake.
This is a sleeper, if more knew about it, I imagine it would become very popular and "Out of Stock" or "Back-ordered" from outlets carrying this tin.
V/R,
Archer
