Looking for the most inconspicuous engine case protectors.

Hey guys, I'm almost done with my bike, but having a hard time with some items, like case covers (wasn't thinking of getting any, but might be a good idea), and passenger peg blanking plates I need to use as tie-downs (started another thread on that). Also need ramps and stands, and will be done after that .

Anyway, back to the subject. As some of you might know by now, I hate aftermarket parts emblazoned with contrasting logos. Furthermore, don't want our pretty engine cases obscured by ugly and bulky protectors. Unfortunately, every protector I've seen except one, involves BOTH detractions (Woodcraft, etc). I already installed frame, swingarm, and front axle sliders, precisely to avoid having to install engine cases. But somebody mentioned that depending on the fall, cases could still be damaged, rendering the bike useless. That left me thinking, and decided that if I find the right protectors, I'd buy them for added piece of mind. And that brings me to the 'except one' part above. I saw a bike with very narrow, nondescript case protectors, but my internet crashed, and never found it again. They were basically just a 'U', mounted with the bottom 4 bolts. Same thickness throughout the half-moon shape, with rounded edges at both ends. Very well integrated and stock looking, just like I want. Don't need or want heavy-a$$ protection with a full set of sliders already. Has anybody seen them? Or any other similar suggestions? I'd greatly appreciate any info you may have.

To finish, a semi-related protection issue I have. My Shogun frame sliders are the 'interference' type, meaning they have a notch that faces the fairing, since they wouldn't fit otherwise (most are like that). Well, the left slider, for some reason, is very easy to rotate, even with the 51 ft/lbs of torque. A tolerance/quality issue, I suspect. But if left like that, it'd probably break the fairing in a fall, since it'd rotate, right? Thinking of removing it and adding a thin washer to add enough pressure to prevent easy rotation, like the right one. Comments welcome. Many thanks.
