What springs?

Here's my plan. I'd like to run 34x10.50 LTB's. I have Bushwackers, and the inner fenders are pretty well clearanced. I'm looking for the smallest lift possible witout extending my bumpstops more than they are now (3 hockey pucks per side up front, and the bigger of the 2 factory rear bumpstops, which I think are 114mm). I have a pretty heavy rear bumper/tire carrier, and the cargo area is usually filled with around 200lbs of tools, parts and stereo gear. All told the stuff in and on the rear is probably around 375-400lbs. The front bumper itself is pretty light, but I'd like to install a winch soon and have it sit level or a little lower than the rear.

So here's what I'm thinking. In the rear I'd like to go with BIGoffroad leaf packs along with my current 1.5" shackle. Up front I've heard good things about Rubicon Express, although I can't complain about the 3" coils I bought from Rusty a few years back. Am I right in thinking that I'll need about 5-6" to clear 34's? If I'm correct on that the 4" BOR leaf packs and the shackle should be fine, and IRRC, the RE 4.5" XJ coils are good for around 6" of lift on an XJ.

Any thoughts/ideas are welcome
