Finished my first bag of lump this week - BGE brand. Being new and having nothing to compare to I wasn't surprised that all the pieces in the bag were the size of a small plum or smaller - lot of it was about the size of a quarter. I did have the sense that I was going through it quickly....only four cooks that weren't very long or hot and burned up a full 20lb bag.
Today I brought home some Wicked Good Weekend Warrior - wow! What a difference. All big chunks, mostly 5-6" and some even bigger. Cooked for a few hours tonight and lots left over. I'll definitely be making a permanent switch to the Weekend Warrior.
