The only issues I've had with the F are I just don't think they have much age on them. The pre-release sticks that were shipped in the 5 packs were shipped with plume already on them, but the regular release Cain F's were pretty fresh. I think they will age quite nicely and plan on picking up a box when I can to just stash in my humi for awhile and see how they're smoking then.
Until then, I still enjoy them, I just think they'll be a much better stick with some age
