I'm not so concerned about my ability to land on a grass strip, as I do it often. More interested in ability of the columbia to handle it. They have small tires that the wheel pants don't leave much clearance for. I really like grass strips. I also like columbia airplanes, but don't know how well they would mix on a regular basis. I have looked in several places and haven't seen anything about soft field operations. Was thinking maybe they were like the pa-46 was and not approved to operate on grass, although, I know that now the mirage and meridians have been approved for soft fields. I was thinking that your rv10 series also had some problems on soft fields with the nose gear?
