I need new shocks

I'm doing the research here...

The two major ones seem to be Bilstein and Rancho

Has anyone looked into a dual shock setup? Is that possible for our vehicle? Does it even make sense?

I'm worried about the bilsteins based on this:

but then this is good

The rancho adjustables seem stupid since most leave them on setting 9 the entire time

There are also gabriels

So the question is which ones... btw.. I'm at 102,000 miles (although 60k have been driven with bigger tires, so probably more).. with the originals.. they are not leaking, but feel not as tight as they used to be... it's time to get new ones. I want them as stiff as possible, I love the bounciness.. and deal with it based on the fact they are the best off-road.

I'm hopefully only looking at like 300-500 range I hope.. but if duals are possible, I'm up for it.. that would be cool, not sure if there's much room up there or if it even makes sense with independent suspension.

Please let me know what you guys are doing with the suspension for a normal vx (no lift, although someday I will, it's just not in the budget right now)
