So it sounds like a pretty even F/R would be the coils up front and a set of leafs out back.
I've decided I'm going to do rear springs for sure and see how I like how it performs front to back. A bump kit and springs is $2500 but at least can be used when I go with 3.0's while the coils become $500 paper weights.
Depending on how you drive offroad, you'll still notice the back end can't keep up with the front. It will stay more planted through big hits, but washouts and things like that you'll notice the back end shakes a lot because the shocks just can't keep up.
