I cube cut when I have time, and rub out in a hurry. But, every blue moon, I will come back to fold and stuff.
My problem with fold and stuff is that I find that I have to fiddle with it during the smoke. Not all of it burns evenly, which is good in some respects, because the unburned parts get heated and contribute to flavor, but like a run down a cheap cigar, it drives me crazy. So, I end up pulling down the unburned flake parts, stir occasionally. And, if I am setting down and in conversation where I can't clench and have to stop and converse, a flake gives me something to do with my hands.
