Why is front shackles a bad idea? I mean shackles at the very front of the frame rails. Would make my SFA easier to do, but I know Jeepers and Ford guys convert away from this setup. As far as I know, it puts lots of stress on the springs and makes them more suceptable to bending.
A rear shackle lets the axle move in the direction that it is trying to go in the first place. 
Would be so easy though
