We are running a spec rotor in a 1688 growing wheat, seed beans, and food grade white corn...large wire concaves, all wires are in, no covers on concaves, keystock grates...an airfoil chaffer helps simplify things but you can make what you have work very well for you. ran a 1460 standard rotor for several years, so far I have found nothing negative about the spec rotor. feel free to email anytime if you need more info.
