Harris - judging from my Askwith and Becker mortas, this wood does throw a very interesting earthy depth into the mix, so a light VA (flake) starts to mirror a GH with its exotic Malawi, etc. leaf. Maybe even a hint of Tambolaka. The 'morta effect' is most pronounced in the first couple of dozen bowls, at least relative to taste. Olivewood is the same for me - at some point the cake dominates the taste profile.
I first got the 2 mortas because of the reputed synergism with Latakia, and found it was so. But I tried various VAs, including flakes, to see what would happen, and was very pleasantly surprised to find a new dimension to familiar VAs. At the time, several years ago, I didn't find anyone else commenting on this wrinkle.
