The good IFS lift kits are pretty dang expensive. With your available parts, I'd drop in a dana44 and then spend whatever $$ you need to run leafs in the rear. As a DD a SA would work fine, and offroad it'll preform better. I guess it also depends on how much you wanna do the rockcrawling as well. If your gonna be mostly hunting, then the IFS would probably work well. My IFS went through the Rubicon just fine, but it got beat on hard. really you just have to figure out what your needs are, and suit your needs.
