SweetPete, it's a location specific deal....

I've run 2per row for more years then I can remember, but it came as a suggestion from Jim after he'd came and setup a neighbors planter....

So with that said.... you've got a couple of choices,--

--find somebody nearby that running then and see what he does

--set you planter up split between a couple variations, go out a week or so ahead of normal and try it out.... Then set all accordingly? (that's how I do my row cleaners to get the initial starting point)

-- set them and forget them....that's still probaly way better then the OEM setup....and what most of us that had the earlyu DAWN recs....
