Best off doing a 1" BL IMO. You will not notice any significant difference between 1" and .5" BL. Heck you won't notice much of a difference doing a 1" BL over stock. When you do a kit like the Daystar BL, you will also have the benefit of replacing all your most likely worn body mount pucks. No reason not to do it.
For doing a Tummy tuck I think best route is 1" BL, 1" MML(and 1" steering riser bracket), and Novak shifter cable. You spend a few more bucks but the results are well worth it.
