OME springs, light vs. heavy: ride quality???

I've been considering what to do with the suspension when I get my future WJ, probably a late Overland. No rock climbing for me -- just trail/powerline stuff connected to my search and rescue missions.
I recently sold an XJ that I'd put OME "medium" springs on, and what was billed as a 1.5" kit actually ran almost 3", which was OK. Ride would be described as "firm".
The OME's for the WJ, however, only list "light" (0 - 90# of accessories) or "heavy" (90 - 200#), no "medium". Plans include a front bumper, rack, maybe a winch. And I have a few "accessories" around MY middle, too.

Since the WJ will also be a DD, what has been members' experience with the ride quality of the "heavy" springs (or the light ones, for that matter)?

Do they do anything to alleviate the old GC wallow? That would be a bonus!

Springs have nothing to do with ride quality. They only contribute to the height of the Jeep. The lighter springs would be more for a stock jeep with no accessories to cause them to sag. The stiffer springs will allow you to put a 200# bumper and other goodies on it without the springs sagging.

Ride quality is going to be dependent upon what shocks you have. If you plan on adding a bumper and winch and roof rack, I would go with the stiffer springs and make sure you get a decent set of shocks (MX-6's or Bilsteins)

Springs do to affect ride quality. A spring with a higher rate and less coils will not move as much when hitting bumps as a spring with a lower rate and more coils.

Uh, yeah. I'll also have to respectfully disagree. I have decades of experience building and operating race and rally cars, and that statement flies in the face of applied physics.
You, yourself, described the heavy-duty springs as "stiffer".

Stiffer = harder-to-press-down.

Harder-to-press-down = firmer ride.

You make a coil spring longer by adding coils. You make it carry more by making the wire a larger diameter, which makes it harder to compress, etc.
, etc.

But I do agree that shocks make a big difference in ride quality. That's why I have a set of Bilsteins on layaway with Kolak!

I was just curious if anyone on the Forum was running the OME heavy's.

How about heavy on the driver's side and light on the passenger side?

OME already gives slightly longer springs for the driver's side front and the right rear. It's the counteract the weight of the driver and the engine torque on acceleration.
