I like 35's with a 3.5" lift myself, then cut the fenders to fit. A 2.5" SL and 1" BL will get you to the same place, but you'll get the added benefit of the BL and less angularity at the front driveshaft.
My rig was 33's with 3.5" SL...looked pretty good to my eye, although my fenders were cut a little high by the PO for the tire/lift combo IMO. I added a 2" BL knowing it was going to evolve to fit 37's, so now it's midway through that upgrade. I slapped some 35's on it with the 3.5" SL and 2" BL in the interim...also not a bad combo, and certainly better than the 33's, but more lift than is necessary for just 35's IMO. I'm going to full-width axles at the same time as the 37's, so I'm going wider to help offset some of the taller part, although she didn't drive too bad on the 33's or 35's with the 3.5" SL + 2" BL combo.
