I nearly forgot about those pictures. I've used these pics before, the joint is a king size L skin. These burn for just over an hour.

All you can really tell from a picture though is how much weed i use, and from that you can sort of judge how tight they're rolled.

The only way to roll PERFECT joints is to practise and practise and practise. It's ALL about the feel. The looks are important too, but it's the burn that makes a GOOD joint, and the tightness. Too tight and it's not going to burn, too loose and it's gone in two puffs. Most peoples joints are good joint, but still too loose. I find alot of my mate cant get the right combo, they roll a good joint that burns abit too fast, and when they try to roll tighter they roll too tight.

Trial and error is the way forward.

Also, notice the roach [card] is slightly longer than the norm - i find this helps to cool the smoke and therefore make it EVEN smoother. Also, it keeps the mouthend of the joint PERFECT, right down to the very end.
