I think I roll average, some opponents think I roll high... its all from what perspective you look at it from if you lose you are bound to remember the lower rolls more and thus you think you are a low roller.
however I treat my dice well and have never bought a single dice since the twenty I bought around ten years ago. They have served me well ever since and for every examination I have ever sat I have brought one dice into the exam with me as a mascot. they show a particular use in the multi choice exams. when i haven't a clue I roll the dice to determine which option I choose... It makes me feel better than randomly guessing
