fully rubbing it out is pretty reliable, so when I don't feel like experimenting and learning more about how to smoke flake, I'll do that. Other times I will cube cut it, fold and stuff, and also musketball method which I've probably had the most luck with. My MM Country gent has a slight conical shape to bowl, especially since it's more caked towards the heel (I smoke lot of half bowls), so wadding up a single flake and stuff it in the top leaves a generous air pocket in the bottom half of the bowl. Works good for wetter flakes as well, since it keeps the last bit of tobacco from getting quite so soggy.
