PN4

I think I have narrowed my choice down to either N-Fab nerf bars or Lund International Rock Rail Gaurds. I use my truck off-road so the stock running boards I have now are getting in the way. At the same time, I can't get rid of them altogether because my wife is 4'11". Does anyone know which of my two choices can take a bigger beating and are more out of the way? I understand they are both body mounted which might make them close to equal. If it matters I have a double cab Z71 at stock height but I plan on a 4.5 or 6" lift in the future.
