Picked some up @ Sams on yesterday. Very large pieces and I thought it burned quite well. Would definitely buy again.
For reference..I have a 22" WSM and cooked an 8# brisket today...had to add maybe a half a chimney to the initial load for the entire cook. I left her going after I pulled the brisket (just curious) and at the 12 hour mark I was @ 200 deg (no adjustments) with a fair amount left.
I have also bought the smaller, 10lb, bags at our local Pamida and they didn't have anywhere near the large pieces that the Sam's bag has...but, in a pinch, it'll do.
will definitely buy this again. 40lbs for 15 bucks.
