Dropped I Beams

I know someone who has a set of Belltech dropped I beams for sale and I want to know if those are easy to use on a bagged Ranger, or does everyone recommend the DJM square I beams to the round ones? What does everyone think of the Belltech I Beams???

when you get done with the rangers, wanna work on the super duty's next?? i been looking at red dogs and been thinking about doing mine but dont want to use chevy parts, mostly the spindle and hubs.
