720 rear bag setup

I was thinking of doing a bag over axle setup, and the more I get to thinking about it, I'm leaning more towards bags on the 4-link bars. This is not my daily driver but when I do drive it, I don't want it to ride like ass either. Does anybody have a setup like this on their 720, if so what length are you upper and lower bars.

The guys at GoEz are bagging one right now.
They did a reverse bag on the link bar set up that is pretty sick looking and the pinion angle barly moves. Im sure it will ride real good.

why not build 2 lift bars for the rear and make it a home-made 6 link?
