Opinions on Leaf Springs and Torsion Bars?

I was going to get new shackles and hangers, so, I figured why not go offset. I don't want any tire or rim clearance problems when I get em'. I don't have much fabrication skills, but, if I really needed to make something I have some buddies that might be able to help me.

If you go with the off set shackles and hangers plan on moving your spring perch on your axle housing.
