Rear Spring Setups for Heavy Loads

For those of you with a heavy rear... what springs are you running?

I've been through 20 or so threads that mention a handful of setups but I thought it would be interesting to see everyone's configurations in one spot.

I'd be interested to know the following:

Spring Make/Model
Estimated Weight of Gear/Mods Unloaded
Estimated Weight of Gear/Mods Loaded
Ride Height Over Stock Unloaded
Ride Height Over Stock Loaded
And most importantly; are you happy with the performance/ride?

I'm in the process of determining what springs to go with after my SSO rear bumper install. I'm currently running the 3" Icons but they are already having a hard time handling my gear and Turtleback trailer. Another 250 lbs is going to require some help.

My current stats are:

Spring Make/Model: Icon 3" "Overland" Edition
Estimated Weight of Gear/Mods Unloaded: 315 lbs
Estimated Weight of Gear/Mods Loaded: 475 lbs
Projected Weight (Post SSO Bumper) of Gear/Mods Loaded: 750 lbs
Ride Height Over Stock Unloaded: 2.75"
Ride Height Over Stock Loaded: 1.75" - 2.00" (Approx)

Thanks!

AirLift 1000 bags???

Not sure if you are talking having a heavy person in the truck, or having weight on the hitch. If your weight issue is only part time, you could consider air lift bags that fit inside the springs. I tow a boat above the max, and by adding 25 lbs of air to each bag, the truck levels out and rides well given all the weight on the hitch.
 
I'm using the Icon overland springs. My curb weight is 6300lbs - full armor, sliders, bumpers, swing out, fridge, etc. The springs handle the weight just fine, the shocks on the other hand, will be revalved in the next few weeks.
