Disclaimer since I am a Beck's dealer, but we are 5 miles from the Minnesota border. We had Beck's Liberty beans this past year that performed well. We had some Stine Liberty as well. Both were good, but our best beans were the 184L4 Beck's. If you look at the Iowa State soybean trials, Beck's 185R2 was the highest yielding bean in the northern district of Iowa. Both 185R2 and 215R2 are really good beans. Here is the link to the ISU trials.
