I probably shouldn't say anything since we aren't done planting yet but this year our Precision stuff has been perfect and it's the first year in the 5 seasons we've ran  the 20/20 we haven't had issues with it.  We are running Airforce and RowFlow running Trucount clutches.  My biggest gripe with the Precision stuff is that they use some very small wires in some of their harness', like 22 gauge or smaller and we've had a few pull apart but not enough to tear the insulation so the breaks are hard to find.  For what this stuff costs they could afford to use no wires less than 16 gauge and I think that would eliminate 95% of the wiring problems and it would make reliable field repairs much easier when they are needed.
