Thanks for the reply. I do have a procomp AAL, but im going for offorad control. The lift doesnt matter, and i dont mid if i loose height to gain traction. Should i run the stock overload spring, the procomp, or none at all? I want to get the back end to stop bottoming out and stop bouncing.
For your stated needs, I would suggest the Deaver 7-leaf prerunner pack. It'll give you about 1.5"-2" of lift, and likely ride like a dream compared to your current setup. Those Pro-Comp AAL's are very harsh, in my opinion. Any of the shocks you mentioned in your first post would work well with the Deaver leaf packs. I believe the 5150's are available in a softer valving than the 7100's, but don't quote me on that. I don't know a lot about them yet, but from what I understand the Donahoe rear shocks should be an excellent match for the Deaver's as well. If I remember correctly, the Donahoe's were designed primarily to be paired with the Deavers, or maybe they just did a lot of testing while using Deavers. Obviously if you go with the prerunner pack, you wouldn't use the Pro-Comp AAL, but you could use a small lift shackle if you needed a little more height, which would not alter the ride but may accelerate the sagging/de-arching of the leafs (they'll sag over time on their own; lift shackles tend to make it happen quicker).
If the full 7-leaf pack is beyond your budget at this time, I'd suggest the Deaver 3-leaf progressive AAL. Most of the people I've seen on here who run them seem more than pleased with their performance. Again, you wouldn't use the Pro-Comp AAL or the stock overload leaf, but you could use a small lift shackle for slightly more lift, if needed.
Perhaps just as important in all of this is to make sure you get shocks that are the appropriate length for the amount of travel you'll have, based on whatever leafs you're running. Once you determine your travel and compressed/extended length requirements, then look at which shocks fit those specs. Once you determine which shocks will fit properly, then look for which of those offer the softest valving.
