If your weight system doesn't extend forward around your hip point the weights won't hold the rig stable and down on you when you turn, and the rig won't turn when you rotate in the water column.
Any trim weights you wear behind you on the tank bands will detract from the feeling of being locked into the rig.
If you have a properly fitted Ranger or Stiletto and are diving a single tank I don't think there's any need for use of a harness for rec diving.
I dive steel tanks exclusively, and I don't use the trim weight pockets on my Stiletto at all. I removed them so the Roll Controll tank holders (highly recomended) on my boat will hold better.
