I don't have a problem going from 220,000 down to 150,000.   I can agree with that provided the seeding tool is good enough to get a decent % emerged.  I do have a problem with the experts advising to go from 150,000 down to the 120,000 neighborhood.  Been there and tried it without satisfactory results, and surprisingly when I read Mr.Ferrie's yield trials I don't ahve any difficulty at all concluding that the higher population is more profitible.  When I read the articles as they made the rounds I was never able to reconcile the data presented in the tables with the conclusions drawn in the text. 

The key to cutting 30" beans with a flex head is to run diagonal to the rows.  I don't know why it took us 'til about 2001 before we figured that out.  

You just missed the only 4 State Farm Show I can remember which has had decent weather.
