I'm not a fan of RockKrawler, hated the GenII lift on my TJ, but I really like 4.5" Rubicon Express for a solid, quality and very steetable lift.
I'm with Yager on this. A virtual lift will ultimately give you the best options. A VL allows for 35's now and leaves the Jeep in a more or less stock build point for later on when it's not a DD anymore and you may want to go really big. Since it is a DD it makes sense to keep your center of gravity lower for street and it will help on the trail too. Add a 1" BL and trim the front fenders and rear wheel wells and you will save a lot of coin for other improvements and have a capable and nice riding Jeep or you could do some Gen-rite, TNT, Metal Cloak, etc virtual lifts which some allow up to 37's with no lift.
Fyi, this is coming from a guy who wheeled a stock TJ then 4" SL, suspension lift, to a 7"SL + 1"BL and now working back to a more stock height because it was much more fun wheeling stock'ish than over built.
