I'll do that...but it's exactly the same thing. roasting in a drum. and extremely popular. on the roasting reddit I asked about drums and a lot of people posted with 10 years + of use on the same drum and grill.Just because you can roast on a BBQ, doesn't mean you should!! Some of RK Drum's marketing claims are ludicrous, to put it politely.
If you haven't already, MrF, you need to spend some time at forum.homeroasters.org/forum/index.php and/or home-barista.com/home-roasting.
