for ql's *******s are good. but as an overall coal i actually prefer my natural shisacos. *******s burn hotter and faster for me, leave more of a mess, and also only last 45 mins (but they only take a minute to light
as opposed to about 8 minutes for shisacos). to me it kinda comes down to how much time i have on me if i have the time and i want a nice long uninterrupted session i go for the shisacos. if im in a rush to get a bowl packed i grab the *******s. kinda wanna try john's naturals next time and compare them the shisacos or exoticas.
