Which do you prefer? I have yet to try lump, but have read numerous great reviews on the internet. I am new to this site, so this has possibly been discussed, if so, lead me in the right direction, if not, let's discuss. For the past few months that I have been smokin', I have been using a combination of charcoal briquettes (Kingsford) and wood chips and wood pieces (mesquite) i/n my Chargriller DUO with side fire box. I just purchased a charcoal starter today, interested in trying it out this weekend. Might be doing a turkey on Saturday for Christmas dinner.
