well, you just gotta play with the results, no one person can say exactly how yours will work out. don't worry, after you take the spring pack down once, you'll get pretty good at it and it becomes not such a big task the next time. i really don't know a better method, just build your pack, I would think the xj main to start with, and maybe the rest S10, the reassemble it and drive it, then adjust from there for less or more height as desired.
