Re: 2 questions for a new guy.
I have heard amazing things about the vortex too. Will that smoke with like 10-15g of tobacco? I know that some of the larger funnel bowls had issues when small amounts of tobacco was to be smoked, and i know the two bowls are similar, with the vortex having holes on the 'side' of the inside... thing? Where the funnel bowl has a big hole on top.
Also, as far as screens go, I'm aware of the metal screen idea, but i just loved the glass idea. If you hadn't looked into it, it is just a glass plate with a hole in the center, raised so it slopes down and out towards the edges. Coals are placed around the hole, but not on top of. No air is pulled through the coal, and the coal has no holes below it, which makes it so there is never a bit of coal pulled into the bowl.
Also, I am using 3 kings coals. I've looked all over the place at coal reviews but none of them really say the same thing so i'm not entirely sure where they stand.
