Honey dutches or anything with a green leaf. Theres a brand called "Game" that ive been trying recently, can get close to an hour off one if its just me smoking it.

When you roll it, be sure to break up the herb properly. Not too fine, not to big. If its too fine, you can get more in there, but it wont flow enough air and often needs relighting. If the chunks are too big, the airflow will be uneven inside, and it will canoe.

I use NO saliva on the paper inside, and just enough on the leaf to keep it flexible. That makes the inside burn a little faster than the outside, its a good anti-canoing technique.
