Most of the problems you have seen are caused by the owners design. You want durability? then stay away from the "drag race" sized rod ends and put some beefy components under there. When you make your rods make them out of heavy gauge mechanical tubing larger than 3/4 inch and make them as long as possible. Gusset everything and TIG weld the whole shooting match together. A nice four link setup with a rocker style panhard assy mounted to the axle housing is probably the best all around, most launch hop problems with this design are due to deflection in the components and inadequete shock/angle damping. Have a look at some offroader type installations and see how they are built, these guys build them tough (not for looks) and can't afford any axle hop at any time.
