Well I believe that I have a pretty sensitive pallet when it comes to pot. I can analyze a stone/high pretty well relative to weight smoked and price and whatnot.

Did you smoke it in a blunt? To me, the tobacco in the blunt will actually dull the high for me. If you smoke dank, you can feel that it is a direct/intense/obvious/pinpoint high. A lesser quality will have a more overall high. I call it a "dirty" high, but its the same 'burnt out' feeling you are talking about.
