5100 Setting Please Help

Ok, so my truck is going in the shop tomorrow to install the 5100s in the front and I'm getting mixed recommendations on the setting to use to level it out. I have a 08 TRD Sport DCLB and here are my measurements from CENTER OF HUBS to fender:

LF : 20"
LR : 22.5"

RF : 21"
RR : 23.5"

I have the rear leaf TSB done as I have a 4 leaf pack. I'm reading that the 1.75 setting will level it out, and also reading that the 0.85 setting will level it out (Read it being recommended for 3 leaf and somewhere's else for 4 leaf). I'm all lost here and don't know what to make of everything. I want my truck to be as level as possible without it being nose high. Write me your recommendations. The more the merrier to make a pool of data. Thanks!

 

Currently I'm running my 5100s @ 1.75 with rear tsb and it's pretty much leveled (doublecab shortbed). Tried it on .85 and I was a bit tail high.
