Very well stated... I have nothing to add to justify my decision.

To the other questions:
Power: I'm not sure what kind of power I'll have at the wheels but I picked up the 430hp crate LS3, so even if conditions are not completely optimal, it should make over 400hp/400tq. Additionally, the 6L80E is a very efficient, low-loss transmission. The transfer case is a stock jk unit with a modified input shaft, so from that point back, the parasitic loss will be the same as any other jeep. Regardless of the peak power, this motor has a great power curve and it uses stock tuning. It will be smooth as silk whether its 5 degrees or 105 degree outside and the shifting will be as good as any stock Chevrolet.

Fuel Economy: The LS swapped jeeps have been reporting better than stock fuel economy (if you can keep your foot out of it). I suspect this is because of the extra gear (.67 high gear ratio) and the fact that the engine makes great torque lower in the rpm range. It stays out of the PE mode, which keeps the fuel mixture leaner. However, we drive bricks, so it will never compete with the Prius.

Brakes: I have the teraflex big rotor kit, but the overall weight shouldn't be much more that what I'm pulling out. The pentastar/W5A580 are lighter than the LS3/6L80, but the sprintex supercharger added a fair amount of weight. Weight is one area where the LS motors do very well. I'm having 35x12.50r17s mounted while it's at Robbie's shop, so we'll see how the brakes perform. The big rotor kit was designed to combat extra weight and larger tires up to 35".

Hope those answers are helpful.
