Mine's SOA. Works very nicely. 30+" of wheel travel, no sway bars or track bars, can still chase the corsa's round the roundabouts. I have the RE SOA springs which still have no sag after 3+ years, rides not too harsh.
Longer brakelines, driveshafts, spring pads on top of the tubes, high clearance steering make it all work.
Sam Fletchers YJ is also SOA, and maybe Jim Waitts.
I don't think its more trouble than its worth, it just has to be done right. I prefer it as a form of lift over some of those U shaped SUA spring lift. God awful ride, not as much flex
