honestly, i feel some people have rolling in them, and some don't. some can roll a few joints and become future-masters of the art, and some can roll 100's and still roll joints where the weed falls out, paper burns slower/faster then the paper.. blah blah ect ect.... my joints pretty much always come out the same. not too good at judging size tho, i put some weed on my little workspace that looks about like a good joint, roll it up and usually end up being alot fatter then i thought it was going to be. but they're always very nice, and smokable.
