artek:Neither- #9FredT
ok, too late
I haven't used Dive Rite, but I do have Halcyon, Fred T, an Abyss doubles wing, and assorted other stuff.
On plates, one of the things I like about the FredT plates is the range of thicknesses and therefore weights they come in. You can dial in the weight that way, add his heavy steel STA, and get yourself pretty close to the weight you need without weight belts or pockets. For example, his heaviest steel plate (a 3/8" thick monster) is something like 16 pounds by itself, 21 with the heavy STA.
As others have done, I'd encourage you to use the Hogarthian rig of a single piece of webbing rather than a harness.
On the wings, I like the donut designs like the Halcyon Eclipse. I don't like the donut for doubles. Whichever way you go, don't overdo the lift on the wing. For a single Aluminum 80, anything more than 30 pounds starts to be overkill and added drag.
