Thanks for explaining the finer points of bean seed production, for that sort of high quality work I would go the STS as well, our Lexion goes pretty good with the changes I have made, HHS interchangeable concave so we can run all sorts of concave and APS combinations and the rotor flow kit and impeller wear kit, all these changes made our Lexion into a far better machine than standard and it is certainly a superior combine with what we do but I could not say it would be a better machine in your situation than an STS, good luck
