I have a combine with a standard rotor, one with a specialty and one with an AFX, and I will say that the AFX rotor will do at least 15% more then the other 2. So many people bad mouth stuff off of hear say and have no facts at all to back it up. It will take a while to work out the bugs on the 7010 and the 8010 but it will happen. They are taking a hudge leap into technoligy so its inevitable that flaws will be out. Westlake harvesting ran an 8010 this year along side of the 2388s so there is a harvester who could give the details on the pros and cons..I believe that the 2388 is by far the best combine out there it may not cut the most acres per hour but they are simple to set and they last forever. I have a 98 model 2388 what just turned 4700 engine hours, I have put very little into the machine other then basic wear and preventive maintenance here and there, I will put it up against any machine as far as running all day long and doing a quality job..
