i have a Tangiers Medium and I love it
I use 3 QL CH coals because I do not have a tall enough windcover yet for it. I already have an order coming in from CH John.
After I get the cover, the small and medium phunnel should be just fine w/ 2 coals. I get a lot of smoke with it. Rumor has it that after you have smoked and an hour later you decide to come back, the full flavor and smoke is still there. This is because of the phunnel design.
As far as for the vortex.... idk the stories i heard about bad drilling holes and the holes getting stuck. I'd rather spend 8 extra on a scalli
