I was in a similar boat as yourself but I was getting my first harness. I was thinking one of the deluxe style ones with more adjustment would be better. I came across a deal for a dive rite transplate harness so jumped on it. I ended up also ordering a full single piece set up from piranha.
The piranha set up you can see below. I went with hi viz green webbing, all black hardware, 2 bent and 2 straight d rings, I went with 4 smooth tri glides and two teethed for the shoulder d rings. The stainless smooth ones are for the back side of the plate for the waist webbing. The black ones will be on the waist belt itself for the d rings.i also ordered a double ended black clip off tri glide for a couple of extra attachment points.
The crotch strap is a dive rite 2” while the trim pockets are dgx and cam bands are dgx stainless.
