We put the P3 stars in an R60 last summer. The crops we harvest are corn and dry edible beans. The high low setup worked well in corn and seemed to help with rotor loss in beans. We did have bean straw that looked mauled with a fuzzy look to it. It is possible that where there aren't any helicals on the separator bottom that the straw isn't being moved well. Whether this is because of the high low bar setup, I don't know.
