David, I got the Option 2 sliders. I like the stand-off tubes and wanted them to stick out more than the slims did. Rock protection is important....but so is protection against an errand Toyota Carolla door! I haven't done any testing yet but I hope those lower doors will hit the slider first and not by door panel. That was the case with the running boards, which one reason I wanted to keep them for so long.
Anyhow, I don't think the car "feels" any different, except at lower speeds there are some different vibrations and tones you can feel and hear respectively...if you're in tune with your LR3. I say it that way because some people post not being able to feel the difference between Sport mode and normal; those folks would not feel any vibrational deltas.
I could take pics but you've seen 'em all before. In 3 weeks I go off-road so that's when it'll be all hopped up with the rod-mod installed and the MT/Rs on. Trust me...it'll be better that way! You think YOU'RE anxious?...how do you think I feel?!?
