I agree with the idea of a rocker lip type of guard. I actually was looking for something along that lines and never found one so, now I run tube style. I really like your idea TwiztedEngineering, but, I am personally hesitant to frame mount something that is in very close proximity to the body with all the frame flex Gm's have. I like the added beef and added protection but, personally I would prefer the exact same edges you make but with only a little bit of underbody extension and a mount to the body's reinforcement boxes (it wouldn't really be a potential jacking point anymore but, it would add some needed beef at the rocker panels.). I would actually be severely tempted to sell my current tube style ones and run a lower profile set of sliders like that! The side profile you've got looks PIMP and your overall design looks great but, that's just my preference. It would bring cost, weight, and manufacturing complexity down considerably too!
