Rizla, Bugler, Elements, Pure Hemp... really, I will go with anything in a pinch, but for preference I will pick RAW. RAW is pretty good. Expensive, but it doesn't break the bank. Big sheets for preference. More work involved, and I seem to recall you get less value for your money, but it's simply nice to be able to decide the size for yourself.
In the olden days, back when I was young, adventurous, and stupid, we would craft multi-feet length monstrosities out of a ton of Zig Zag or Rizla. It would be so much easier today, although I think I've gotten too old for that sort of thing.
