Re: opinions needed on suspention ideas! (long)
I have personally ran lifted springs, SOA, 4-link with air shocks, and have built 3 and 4 links using coils and 1/4 elliptical.
I had quite a bit of flex in the rear of mine SOA and spring packs I built, I could use all the 14" of shock I had. I went on a couple day runs with friends that I had built/ or helped build various link set-ups and was amazed at the performance, and how each style system reacted differently and kept going back and forth for awhile myself. Currently I have a little more flex than before (about 2" do to shock mounting location) with the 4-link and air shocks, but I was more after the performance difference of the link set-up, and the flex was secondary. With the link set-up I was able to tailor it to what I wanted and the way I drive. Turns out the rig does exactly what I want it to do, has no axle wrap, and rides better than the SOA.
From what I have found, SOA or a link set-up can both flex great and work reliably, or they can both be crappy. It really depends on how well it is built and what is used.
Longer, thinner leafs flex better in SOA, and tinkering with other leaf packs you can get some great spring packs, the downfall on them is axle wrap, so a traction bar is used. With four links you can get huge amounts of flex depending on shock location, have no axle wrap, but if built wrong you can get some strange handling issues, and rear steer is possible with any link set-up but can be lessened. My rig has an extremely small amount of rear steer throughout it's full range of travel.
