Actually we've never tried either. They are probably good plots - but I never buy a blend unless I know exactly what is in it. I wasn't able to find what is in Full Draw, but its probably a brassica blend. I hear its a fall plot, and I have heard people say good things about it.
Biomaxx though is an expensive Roundup Ready Soybean and Roundup Ready Corn mix. We mix RR Corn & RR soybeans all the time, however the beans are never as "strong" as those grown out in the open. We mix them where corn & beans meet. Of course we spray with Glyphosate.
Prepare your soil well, it probably means as much as any type of product you might use.
Good luck in your Onondaga County plot - post your progress and I'll be happy to help if I can with advice.
