The first two don't always get rubbed. I rub out the milder flavored ones like Virginia flakes (similar to FVF & Bullseye flake) but the stronger blends (think G&H dark flake and ropes & twists) I try to keep intact as much as possible - that usually means fold n stuff or cube cut for those. SG chocolate flake I like 'crunched out' where I just smash the flake up some with my fingers but leave lots of chunks and some finer ribbons. I like G&H Louisiana flake 'crunched out' as well.
