I am a big fan of the 5/5/2/2 schedule. I always get the kids on Mon/Tue. I have Wed/Thur for myself. And we alternate Fri/Sat/Sun. It has been working out great for 2 years.

But we never had any issues on setting up the parenting plan between us. The complications are for the financials and it is best to let the 2 L's haggle as it gets difficult for the divorcing spouses to do the business talk without having emotions getting in the way.
