professional/competition gets to temp faster, burns hotter, and you have less ash. I'm a blue bag guy though. Flavors were more popular when the flavor dust was throughout the briquet rather than just on the surface
Just moved to the 22.5 smoker from a Brinkman. Pretty close to retirement, 38 years with Goodyear, 8 with Kingsford, and almost 1 with another Clorox division...cat litter.
Thanks
