Ironman springs vs Dakars

So I'm trying to decide on the final plan for my lift. I'll be buying parts in the next few weeks or so. I've decided to go with 6112's for the front. I only want to lift the front 2" or less to avoid needing UCA's right now. For the rear trying to decide between dakars with b110 bilstines or 5160 with Ironman 2" rear springs.
I can sorce all these parts (aside form the b110's) locally. The Dakar setup will come to $170 more. For weight I have a canopy that weighs under 200lbs and quite frequently 100-150lbs of kayaks and gear. Would the 5160 ride that much better on washboard fire service roads and daily driving? I would like to here from someone with the ironman springs about wright handling. From searching there are very mixed reviews.

 

Really just want to hear peoples experience with the Ironman springs with around a 200lb constant load in the back. I can get the whole setup, springs/bushings/u-bolts for around $300 where Dakars will be $600+ u-bolts/bushings/etc.

 

I have zero knowledge/experience with Iron Man Leafs...BUT, I run full Dakar leaf packs and love them.

Ive heard horror stories about squeaking.....but something must have changed over time because mine have been dead silent for almost a full year now.

My stock 3+1 packs squeaked all damn day long
