Rear brake options

Guys, can we get back to my question? I own all 3 options. So I don't need to buy them. I'm torn which way to go. The drums are a perfect fit bolt on with no issues at all. The Willwoods need an extra adapter cable for the "parking brake". The master power kit would be good also since the fronts are also Master Power. Reading the descructions, this kit is the most complicated. I'm sure braking efficiency can be an issue if the rears brake better than the front, the rears will lock up. Most after market brake companies suggest an adjust able pressure valve to dial in the system. So I am not concerned about the lock up issue. I have a all the tooling needed to make my own lines and flares. Thanx..
