Going to do some experimenting with lump over the next few cooks. Always used briquettes until now. I always fill the ring full of briquettes and add hot coals from my chimney over the top. Throw everything together and everything cooks great. I just always have the thought of fillers and other additions going into my food. So should I change anything with my startup process. Use less coals in my chimney vs briquettes? Both on my 22.5 and 14.5. Last, do you lump cookers get more ash blowing around in your wsm. My performer sure does.
