I started off with (what else?) a flake: this time Erinmore. Later on, I had a nice big bowl of my newly-acquired bulk MM 965. At first I thought, "hey, this isn't 965!" It seemed quite different, and not ... Dunhillish. But then as the bowl developed, I realized that:
1) it has been several months since I finished my last (and first) tin of 965, so even if it was identical I may not necessarily recognize it. Since that time many of my English-types have been periqued (Nightcap, FMotB), or SMM which I remember immediately thinking was quite different from the 965 when I started it. These may have skewed my memory.
2) even if it is different, it's so good that I don't care.
