Has anyone tried running all rub bars and no paddles across the discharge end? It looks to me like the paddles do more harm than good by try to compress the straw and lump it togther as much as throw it to the chopper! I have 3000 hrs. on my R-62 and the backing bars are all bent were the paddles are mounted. It's obvious that there is a bottle-neck created at this point. Why even use 1/2 paddles?
