I would go with the 20/20 and Deere flat disks rather than esets. What the esets cost will buy a lot of brushes for the Deere meters.

20/20 was worth every penny and allowed me to adjust the double eliminator pefectly. Also was an eye opener on planter speed. Some places I was able to go 6.5 mph. One field I did was gumbo that was like concrete it had me down to 2.5 mph. Stand and spacing turned out very good in that field. If you had told me when I was planting it that it would make anything I would have called you a liar.
