use the roach, imo it hits better and as stated above, you wont have to deal with trying to squeeze the smoke out of your jay, as for blunts theres no point i dont use them the rollie provides enough support, if you have enough weed in there. On another note, whenever i smoke blunts and it gets to the roach, and i cant hit it with my lips i just hold it up to my nose and suck air in through their hahah gives you a very wierd feeling for a min and gets you really high, not to mention its funny as hell.
