We ran two 8010's last year in Manitoba(wheat,barley,canola,rye,flax). one with a small tube and the other with afx rotor. We are happy with the small tube in all crops and will get it in both combines if we trade. We did have a white cap issue in wheat but 3 hard thresh concaves in front and cover plates on front right made a big differance. We also removed the 4 straight sep bars and installed spikes to quieten the rumble when tough. The sample between the 2 combines was ok,the small tube gave us about 10% more capacity according to the bushel/acre counter. Do be aware the small tube is a nightmare to unplug sometimes!
