If you select the SS DSS plate, DSS has a Glide Harness Adapter (GHA) that is proprietary for their plates which allows one side to slide ($50, IIRC). This makes doffing/donning much easier. I find it very beneficial as I have shoulder issues.
As to the weight pockets by XS-Scuba - they are $9 -$12 each....(worst case, $15 if your LDS is gouging), not sure what you are looking at.
Pick what you want, but if you poll here, there are literally dozens who thought they just had to have the "fancy" harness, and after a short time, changed to a basic one (yep, me too), and the fancy one is now in a bin, or gutted for some basic parts, or sold on e-b$$ for nothing (so you bought twice, and spent a bunch the first time)..... Your money, your choice.
