I've got a tin of Capstan blue open now. I've been enjoying it and,although a certified nic wuss, I don't find this to fall on my list of nic monsters to avoid. The flavor reminds me a bit of Dunhill flake. Have a tin of the yellow, but haven't popped it yet. Both tins are mixtures,not flakes.
I think both are worth exploring, assuming that you are not expecting to be hit over the head with flavor or nicotine.
