It does a great job at keeping dirt off the linkage and dropper. My KSL is a good example of that, with the linkage and shock being so exposed:

Also, more on topic with this thread - I was able to get my first ride in on the new regular CC link and E-Storia, and I'm absolutely blown away with the shock.
Between my KSL and Enduro, I've put about 5,000 miles on DHX2's and have gotten them as dialed in as you possibly can. I never believed the hype with EXT's, thinking it couldn't really get any better than the current DHX2, having independent adjustments for high/low speed rebound and compression, but the E-Storia on my Levo has the rear end feeling better than my KSL or Enduro have ever felt. The best way I can describe it is it just keeps the rear end very composed and keeps the rear wheel in constant contact with the ground.
I even changed some settings in the driveway to get it feeling balanced with the fork, but once I got out on trail, I did some more fiddling and actually ended up right back at their original settings for rebound and compression, only dialing in the HBO a bit more. I sent them a riding video and went into great detail on my setup preferences, riding style, and terrain, so it's super cool to see they actually listened, interpreted it all correctly, and set it up properly. This shock is so good, the front end now feels bad (as someone else mentioned above with their Ohlins), so hopefully, the Smashpot showing up next week brings the two ends closer inline. Without a doubt, this is the only coil shock I'll ever buy from now on.
