Spent a while trying to get mine right. Completely agree that setup's are personal and subjective. You must weigh your truck before doing anything. I haven't listed anything technical about handling below, just how the car felt to me.
I went through:
1. Std 2011 110 Springs + Std Shocks - So much sag and I found the handling inconsistent/floaty especially once loaded up.
2. Genuine HD 110 F/R Springs + Std Shocks - Front sat too high, Rear too Low. Handling was better but still inconsistent/floaty.
3. TF Medium F/R Springs + TF Pro Sport 2" Front Shock + TF Big Bore 2" Rear Shock - Handling was softer than standard, better controlled. Went down the track of dislocation cones etc. I had endless problems with the rear sway bar inverting regardless of what I did. The Rear dislocation cones were so noisy too.
4. TF Medium F/R Springs + Pro Sport + Std Length Bilsteins (Rears are the firmer version) - What a difference, but was a little firm on road and lacked flex off road in the front. Front sat a little too high, Rear a little too Low.
5. Les Richmond Springs 180lbs Front, 320lbs Rear + Std Length Bilsteins (Rears are the firmer version) - In love. Can definitely be firm on road over small bumps but it never feels too firm and never feels out of control or floaty. Off road or on large bumps on road the control is amazing. Flex/grip off road is excellent too. Bump stops are about 80/110mm loaded F/R.
It is worth mentioning I setup my fender for touring with weigh split of around 1000/1800 F/R.
Hope that all makes sense :)
