My old Pioneer I had was drilled negative (5 x 6 1/4 with weight hole near NAP), ball worked great off of the dry. Not too jumpy but skid city in oil. Played up 5 and could carry light hits all day. Had the front 9 with it 3 times the first 6 months I owned it (which was good considering I didnt use it that much).
