I prefer the cone shaped joints, but instead of buying pre-rolled cones, I make my own. Just carved a piece of wood into a small cone shape, sanded, treated, and tada instant home-made "rollmate" like you see on that site rollmate.com or something...
I love these things because if you can't roll that well it makes it very easy to do. Just roll the papers (I use two) around the roll mate, seal it, slide your cone off the roll mate, load roach (small rolled up piece of card paper), load weed, twist end, light and enjoy.
