Sadhus: "Something I'd like to see is something better than the hard paper filter. Long, light, solid, absorbs heat.. that would be good."

When you said that it made me think of this cool reed type plant that grows in the bogs and mountains around here.If you strip the green outer layer, there is a cool natural sponge like filler. I think that would make an interesting natural filter type thing. But really, would you be bothered with that..I may try it sometime.
My usual improvement thought is if I'm having trouble getting a nice tightish roll for some reason (blazed, shaky hands due to cold whatever) is to use the credit card trick. Its funny, in all the threads about how to roll and shit I never see this simple method that gives a perfect tuck every time.. Anyone else ever hear of it? Basically you use the edge of a card to get the tuck right, it gives perfect control of how tight, loose it is and what shape you want cone or straight like. Its really quick too. If anyone wants more detail of the method just ask.
