In the quest for the perfect papers, i've had black OCB's, silver rizla's (+ slims), Smoking Black (+ slims), and Elements rolling paper. They are all ultra thin rice paper type rolling papers and are all excellent, however I find that they have this weird taste that gets stronger the closer you get to the end of the spliff. Sorry, zig-zags are like the mexican brick shwag of papers. Might as well roll up newspaper in some corrugated cardboard and smoke that.
In my experience the smoothest papers with the absolute least taste has been the Blue Mascotte king sized. It's like papers made for a stoner king. They also give a nice even burn and don't burn too quickly or too slowly. They give you a lot of paper though, so I either inside-out-roll or shave off 1/4.
good lord i love joints.
