Arrrghhh! How could you "rub out" such a magnificent flake?!?
Well, that is what my first reaction is. Harris is bordering on heretics with the cube cut, but, I admit to indulging if I am in a hurry and it is not yet at sufficient moisture content.
It's just that when I see someone say that they've rubbed out a whole tin, or worse, one of the bulk boxes, I almost cry. To each their own. My only concern is that they are missing out on a sublime experience by doing so. I've tried it rubbed, early on, and it is a completely different smoke, flavour wise. To some, that may be the right change. To my tastes, it's a pale comparison to the full flake experience.
I think with flakes, and especially this one, the major trick is in having enough space in your pipe for expansion and to make SURE you do not push it down into the bowl. A loose fit will turn tight with fire, in my experience.
This one is incredibly easy to overfill as it expands (maybe due to the higher moisture) and that makes for an awful smoking experience. Too hot, too much steam, too little everything good.
When I smoke flakes, they perform most magically when I use less than what I think I need. It's something I trick myself into. I pull out what I think is enough, then take off 1/4 of that. I don't want to, but I force it. You'd think I'd have it figured now, but for some reason, always taking off 1/4 of what I pull out works wonders. Then I carefully load it to not make a dense plug and after the light when it gets going, it fills my pipe.
Rubbed out? Meh.
Cubed? Well, ok, if you're lazy and in a rush...
