I myself would stay with the Red ones, I am sure you would get along fine with the green one but your heads will fit right off of the 1660 and on to the 1680. You will be amazed with the difference in the 80 vs your 60. The rotor difference, the cleaning difference, and the horsepower. I highly dowbt the 9500 will out perform the 1680. The Red machine is a much easier machine to work on and maintain. I have never harvested soybeans before so I couldnt tell you anything there but I will promise you wont be dissapointed with the job you will get out of the 1680 in corn..... Well good luck to you on wichever machine you choose to purchase
