The short answer… a latitude method top panel with an archon lower panel would be the best 2 panel saddle.
Both are great saddles. The problem I have with the ESS, recon and “I haven’t tried it but I’m willing to bet”… the transformer, is that they have rings which just settle in where they want and therefore you can’t control the pressure points. I’m not saying the ESS isn’t comfortable, it is, but I would prefer it more if I could control the pressure. I’m thinking about cutting the D rings off mine and attaching a bridge right to the panel straps with prusiks.
I have a first generation dryad drey and I knew immediately that it needed to have a different cut to the material. It gave me bad pressure at the top and bottom because it was a rectangle shape. The new version of it is rounded at the top and bottom, and I bet it’s dynamite paired with the saddle you already have.
That CGM backband looks great too but I know nothing about it, or the timber ninja or the buzzard roost.
From the saddles I’ve used I would say…If you run heavy pouches I say the method 2. If you don’t run any, the archon or the drey.
