Another thing is that a guy i work with has access to a hickory
orchard (it's in his family} and he recomends using basic cheapo
charcoal from wally world and using the hulls from the hickory nuts
because they have a higher resin content than the hickory wood chips
and therefore give more flavor with less material.

Welcome aboard, Mark! Ist time success makes that 2nd time success even
better!
I'd be careful using nickory nuts & hulls. They're really a hit and
miss proposition - if they're the wrong species of hickory or a tad too
green - you'll be sorry. The wood is a much safer bet.
Botanically, pecan is essentially 'hickory's cousin'. You might wanna
locate some pecan chunks for your first time smokes. It's a little
milder and harder to oversmoke with. Sadly, though both these woods
are hard as a rock to cut.
