Re: First Impressions...
yeah dont know about the MYA jumbo bowls, but on a medium clay bowl i use 3 natural coals, and its just right. play around iwh t a windcover or some foil crowns to gett he heat just right. you can also experiment with how much you pack and how tightly its packed.
try a few and see how you get on. i really like nakhla, but watch out for that buzz if you are not used to smoking!!!
