My suggestion is to try Old Gowrie first, then Marlin Flake, and Hal o' th' Wynd last. To me, Old Gowrie is more subdued, dark and grassy, mellow and sweet (but not too sweet), while Marlin Flake is dark, tangy, a lot less grassy, and sweeter. As yet, HOTW and I have never really hit it off the way I have with the other two. To me, it's sweeter than MF, but also tangy to the point of being sharp to the palate, and burns hotter than the others. It has been a few years since I popped a tin of HOTW, perhaps it's time to revisit.
