Welcome, Sparky, although I've seen you around before

In my world, SWR means standing wave ratio, but I'm sure it means something else here. Would someone please enlighten me?

As far as recommendations go, @Emperor Zurg made some good ones. I would add Cornell & Diehl Pirate Kake, any of the C&D burley blends, and Peter Stokkybe has some good Virginia flakes. There are thousands of different pipe tobacco blends, so my advice is to get a pound or two of every one of them and start smokin'!
