The compaction problem is more of a problem for me in conventional till than it is in no-till. The last two years, with the excessive rains and record flooding we've had "here", we've had to rush things and plant in  less than perfect conditions. It's been pretty obvious who runs Kinze planters and who runs other makes after the beans emerge. I've seen more poor stands behind transport wheels the last two years than I've ever seen before.
I don't mean to be knocking Kinze planters, I run one and have for the past 15 years and really like them. Lots of pros to offset the compaction problem and under good growing conditions, IMO, there is no yield loss. But it can be a problem, under certain conditions and in a lot of different soil types "here".
