Thanks for all of the replies!
Andy-Because the 800 series internal requires a conversion kit for the 650 body. They are not only difficult to get set up, but also do not hold adjustment that well. I have tried that, and once you do get the conversion kit in place, you can not remove the internal with out it being a tremendous hassle for my hourly employees(we do a lot of hand watering). Pressure is not an issue for us. I would love to have 800s, however, do not always want to change the body when a rotor stops turning!
