I got 189 turbos this year after I sold my 188 crjs and I must say because of the snow we get here in Colorado, I am a lot happier with the 189 turbos. The ski is GREAT for everything above treeline on non pow days and amazing everywhere for any powder day. I have them mounted where they should be at traditional so they were perfect for deep days at Wolf Creek. I think if you mount them traditional they will be ideal in deep days, however, if you mount them more forward, they will not be as ideal as a rocker ski mounted forward of course.
I was not a fan of the CRJ simply because it was too short and I do not see the benefit of rockered skis that everyone else sees. If your skiing in bounds mostly with the turbo at a resort that gets tracked out fast (which is most resorts in the US), I would strongly suggest the turbo. Most big rockered skis are more beneficial in my opinion as touring skis or backcountry only skis. I am 6ft 175 and they 189 is perfect. It skis kind of short as well being as it has no rocker. I got the model with no early rise as well which I love.
