I've skied all but the Backland 117 (own and still love the Atomic Auto 117).
I loved the 18/19 Rustler 11 180, 188, 19x. The 180 worked as playful; kind of like the 184 Bibby. Surprisingly good in crud/chop.
The 19x was a surprise to me: I loved it (me 5'10", 150). It was more stable in crud, noticeably more stable at all speeds fore-aft, very easy and not really too burly from length. After both those skis, liked the 188 least: not that much more stable than the 180, not as playful. Big difference in stability with the 193, without being harder to turn or control. But great skis all three! 5 stars, 4 stars, 5 stars.
I owned the first year 186 Confession. Sold it quickly, for me a mistake at that length. I tried later year's (19/20) 186 version also, to see if it has changed enough. Nope, not for me.
From what I can gather, only the longest version, 190+, seems to be stable enough in crud, to me. (Yellow Gentian/Craig review agreed with me on this.) And the Confession gets hung up in drifts, edge won't release, unpredictably, just enough to have to ski more defensively, in my case. (Blistergear agreed about release.)
Man, but it's tops skiing groomers! 3 stars at 186.
The 19/20 Kore 117 I just finished demoing in 2-5", then crud. Liked it. Good in mild crud. At that amount of fresh, did everything well. (Not as good on groomers as the Confession, but light and good there still.) I'd like to try it in deeper to tell about real powder and crud, but it seemed like it would be fine there, dunno. 5 star so far.
