Steve, some of the things the 20/20 will tell you have been a real eye opener. I thought I always knew what speed and pressures I should be running in the past but there have been situations where I wouldn't have been running near enough and others where I had too much.

Some real gumbo it had me down to 3.5 mph to keep the row units in the ground. Other stuff it showed me that I could run faster than in the past to get more done. Unless you're planting into rough no-till ground 6.5 mph no longer scares me. It also told me that ProMax 40s work just fine.
 
Rees ran one last spring. Never did find out whether he got it working right or not.
