+1 on the Bright CR Flake. I'll throw in Glengarry Flake as well. It has a slight honeydew topping but it just adds a slight sweetness to the palate. Both Gawith houses really know their flakes.
I can't really add to the flakes mentioned here because most of my favorites have been listed. +1 on the Twist Flake. I have some that have been cellared for over a year and it is one of the most surprising flakes I have had yet. I also really enjoy Erinmore Flake.
