House will be in northern Michigan, very concerned about moisture issues with zip sheathing as that we have fairly cold winters but humid summers. Havent really seen great research on the issue. Looking for thoughts/experience with this issue.

What exactly is the concern? Zip sheathing is not a vapor barrier, so would allow movement of water vapor in or out depending on whether it is heating or cooling season.
What are the other details of your wall? Are you going to have a rain screen? What interior insulation are you using? What are your air sealing details? All of those will have more of an effect on vapor and moisture control than zip sheathing. Have to remember that the zip is one part in a whole wall system.
Was looking to wrap wall in Tyvek or Greendrop instead of zip sheathing as an option. Concerned that I could get moisture in wall with the zip sheathing but would like to hear options.
