Need Rotation Advice

Well, I'm sitting here contemplating what rotation I'll begin next. This is one of my favorite but also one of my most frustrating activities. I love playing around with rotations, but it's not like I'm an expert at knowing what's best to do. My first idea was to do some 3-day split workouts for a few weeks. Then I was thinking how I need to lose weight but I also need some rest and stretching so I thought of alternating hard-hitting circuits with Pilates/yoga days. Any advice? Here are the details of both rotations:
