I doubt you'll see much difference with different shocks. To test, just remove the front shocks altogether.. "no dampening" would be the softest possible setup, then adding back shocks would only stiffen it.
I remember my brother's 40 had the Hell For Stout springs, and yeah same deal... that's when we realized that HFS stands for Holy F$#ki*@ S%i! these springs are stiff...
The OME Dakar springs will be much softer, if you want to upgrade. Or a set of stock springs with an add-a-leaf, for a more budget 2-3" lift that isn't as stiff.
