If you like the HOG brand, consider a plain backplate-and-wing (BP/W) configuration, without all the padding, such as this combination:
Hog Stainless Steel Backplate
Hog Hogarthian Harness Basic
Hog 23lb 360 Wing
I can't speak for others' experiences--though many here on SB seem to prefer avoiding unnecessary padding--but I had a Zeagle Express with shoulder and back pads, and after a while I removed the shoulder pads, then a little later removed the back pad, as I realized it wasn't really adding to comfort as much as I would have thought. Underwater, especially if you're wearing a wetsuit, the padding doesn't add comfort--it's only on land that it cushions your shoulders and back. The only reason I can see padding being helpful is for shore diving, where it might make a long walk from the gear-up area to the water more comfortable.
