A lot of guys may give me grief about this but I recently had the same experience with OGS flake. I tried it in a nice briar that I just cleaned and got ready for the first VA bowl... and it was not at all what I was expecting. Then I waited a few days and tried it in my MM cob and it was wonderful! I have two more VA blends and have found with both of them that I enjoy them more when I smoke them in a corn cob pipe. Maybe this is because of the natural sweetness of the cob... but whatever it is I'm using a cob to break myself in and learn the VA flavor before moving into a nice briar.
