Re: Packing Nakhla
I usually pack mine dense (irregardless of the bowl, in all honesty they all smoke just about the same when packed right), I sprinkle the shish a little above the rim and then just pack it down dense below the rim (so the foil doesn't touch it), some people sprinkle some more on top after the pack down, I don't, and it works great, good smoke, good flavor and it lasts longer.
I rarely do the overpack anymore, but it gives great clouds and flavor, you'll just be using twice as much tobacco, Dee has a how to vid, check that out if you want to try.
