I also use the HSS system and haven't looked back. I really like mine. Easy to put on, big buckles so no fumbling around in the dark, and the mesh makes it impossible to get the straps screwed up. I highly recommend it if you are looking for a quality harness system. Not sure how big you are, but I bought the Pro System on in their biggest size, and I'm 6'10" 350+, and the thing is plenty roomy for me, I think the definitely run a little big. You may want to buy one where you can try it on first.
