Well, i normally use between 1.5 and 2 grams per joint, somtimes less. I supose it all depends. Tightness is an issue, but not too much of one. It's hard to get perfect because too tight and you can hit good, and too loose and the joint disappears in 2 hits.

I was going to make a tutorial but i need a camera to show what im talking about, and i havnt got one, so im waiting on a mate.

One day it'll be up here.

I might even make a video of me smoking one for 45 mins straight.. although it'd ahve to be on googlevideo as youtube dont do 45 min vids... then i can prove myself to eveyone... since hardly anyone can actually take my word for it.
