Hi ChiroTrev,
Unfortunately, this question can only be answered by you. There are all sorts of different harnesses, and having owned a shop for about 15 years, on many occasiona, I have had two mates come in and need a new harness, they will both try on the harnesses on offer, and normally, both will chose something different.
Unlike kites or boards, the harness is the only piece of gear that is in direct contact with your person in a major way. Your body shape, skeletal structure and more are different for every person. A bad kite, or board will not cause you physical pain like a harness will.
I would advise going into a quality local store and trying on a few different harnesses and load them on a loop attached to the wall above, to let you know how it feels in a loaded situation. Most harnesses feel good without load. If you are lucky, you may find a superceded or cheaper harness which will serve you better than the latest high tech offerings. You just wont know unless you try them on personally.
