Re: CocoNara vs Exotica vs ******* Coals Naturals
Coconaras suck for the price/amount ratio... but they win for everything else (heat, ash, taste, longevity). ShishaCo coals are a good compromise between quality/price. They are close to CNs in terms of performance and useful life, but they ash a lot more.
CH nats are decent but I dislike the fact that little burning rocks detach from the coal when you move it around. I once accidentally dropped a CH coal from the bowl and it crashed-landed in the tray, sending dozen of red hot rocks flying everywhere and leaving permanent burning marks on my carpet and table. But that's just my horror story, if you're not a dumbass you shouldn't have any trouble with John's coals.
Haven't tried exoticas.
