A predecessor of Irish Flake was, I feel, SG Bracken Flake; the topping and the flavor were similar. I smoked quite a bit of it until they changed the recipe. It took about 50g before I liked it, and the more I smoked it the more that liking increased. I hoped that the recipe might revert and brought some again twice, and not being what I wanted, jarred it, my first remedy at that time.
When Irish Flake came out I quickly liked it and accumulated 89 tins, which I sold to buy cigars. At that point I'd been smoking it for a year or two, and after selling my stash, smoked it off and on, but I never recovered my fondness for it; some tobaccos get lost in the shuffle.
But also I never felt good smoking tinned tobacco due to cost. That was one of the reasons for my overwhelming fondness for DF, whose flavor and strength are very strong. Gets my vote!
