I am. I've run OME on my TJ and XJ. The general spiel is, its not engineered solely to provide an increase in ride height, but to improve upon all attributes of the OE suspension with minimal compromise to the base platform. In other words, you're improving comfort, handling, maximum payload, and ground clearance, while retaining the everyday usability of the vehicle as it was designed by the factory.
That's the theory, though. While it looks great on paper, any amount of lift may generate driveline vibrations and require driveline angle compensation in the form of a transfer case conversion (preferred) or a crossmember drop. Also, while the suspension might boast "improved comfort", those aggressive light truck tires you plan to install might have the opposite effect. That's just food for thought. Keep in mind, the more you do to your Jeep, the more you have to do to your Jeep.
OME is a great option if you are satisfied with no more than 2-3" of increased ride height. However, many folks feel inclined to coax more lift from their vehicles (once they've been bitten by the bug) only a short time later. In which case it might be more cost effective to start with a budget boost until you've established your needs. The Rubicon Express kits are also popular, well-engineered solutions. OME shocks are also available for taller suspensions, which may offer the best of both worlds.
I've run Pro-Comp (not worth mentioning), Rubicon Express 4.5" on a Cherokee much like John B's which performed well, and OME. I favor the OME due to its aforementioned qualities and how it responds to the terrain. The vehicle feels balanced and rolls over obstacles with grace and aplomb. The low ground clearance does limit the trail selection somewhat, but I've also found it to be advantageous on steep terrain due to its low center of gravity. And of course I've retained the Cherokee's best qualities as a daily driver.
Good luck with your decision!
Man I love the way you had that thing in this pic! Did it rub with the factory bumper? Is it the HD kit?
