This is the set up I went with, "stock" height groove on the front, the big thing for me was the dampening adjustment for towing the the rear as my trailer is about 7800 when loaded. I still have the squat issue all rams have so I added the bags to pick it up some before I bought the falcons, night and day difference with the falcons though. As far as the Panhard bar it looks just like spohn and everyone else adjustable bar, only reason mine was cheaper is I have left over materials and I am a welder.
