because i smoke js with some tobacco, i usually put a litle more tob before the roach, so i dont have to burn my lips. Or i use a long roach (most of the times) so i can have space to hold my j. Im not so crazy about roaches, i like to have big fleshy js and i usually toss the roaches if there's a hit or less left, im just not gonna burn my lips, im gonna roll another
