1st Gen lift help

So I just bought an 01 4x4, going to build an expedition type truck, I've had a 2nd Gen that I did full ome and built right ucas, then swapped the front for total chaos long travel and kings all around.
for the front I'm planning on ome struts and 883 coils, Im at a delima for the rear springs I want to have good flex/articulation while off road since I go out alone often(yes I know, should have a buddy) and more flex means the tires stay planted longer equalling better safety.

Without getting to custom leaf packs what would be my best option? There are the dakars, expo pack, Deaver 10-11 leaf pack, what else will hold weight (topper and minimalist camping gear, tools, and at times possibly pulling a small trailer

Are there any deals on uniball ucas for first gens? The stock arms have some rust and I'd rather just upgrade and replace while I'm in there.
