I own the Santa Ana 100 from 2016. I absolutely love it. I demoed the Santa Ana 100 this year in conditions that were not bad for a 100mm under foot ski, and it is a LOT more ski to maneuver, than my 2016 version. That being said, it was a REALLY nice ski and was much more smooth in the cut up stuff I was skiing in. I would like to have tried it in the shorter length (161) because I think the 169 with that beefier construction was just a lot of ski for me to get around on.
I also have skied the 2017 and 2018 Santa Ana 93s, which are also different construction from each other, and I like them both but could easily be swayed into owning the current version (which I demoed again this year.) Stable, smooth, and easy. More serious than the previous version which was lacking in stability. I could see the 93s being a solid one ski quiver for a lot of women.
Really nice skis overall. I seem to have a taste for Nordica and Bizzard skis in general.
