Short vote: Starbuzz.
Starbuzz would be flawless if not for their horrible consistency problems. Starbuzz gives off huge clouds, comes in a great variety of flavors, and the flavors are usually pretty good. But consistency is terrible. One batch may be the best tobacco you ever taste, the next can be unbearably bad.
My homemade shisha just won holy fuck was it crazy awesome flavor huge huge clouds and best of all no fucking stems whooo be on the look out for it its gonna be called Christ Thorn 666
