i think you will find that people like us are in the minority. most people i've met, even on here, don't use a roach or crutch or whatever their term is for it. i do and i put it on the left every single time. i am right handed. are you left handed?
Does that question even make sense? Inst the left side of a joint the right side also if you turn it around? I call it a filter, and I normally roll my joints with one side bigger then the other, coner style, and the filter is always put in the small side.
