I owned a Bonafide for between 5-7 days this year and as much as I LOVED the ski in any condition I chose to part with it for the lighter Kabookie. Halfway through the days the heavier Bonafide was affecting my knee, heavier swing weight skis do this to me but was hoping it wouldn't be a problem because the ski was so nice. After demoing a kabookie over the course of the weekend I knew it would be the better option for me.
Today was my first day on my new Kabookie with firm, fast, and icy groomers, AGAIN. For people wondering is there that much difference between the two skis my answer is yes and no which is a good thing. Bonafide has more bite on icy slopes, little smoother and damper at higher speeds, and in the same lengths won't ever get overpowered when pushed really hard at high speeds. But I will say this, if you have never skied the Bonafide you will think the Kabookie is all of that, unless you are quite a bit heavier than me or huge racing background. It is a great ski despite not having any metal in it!! I traded a slight loss in overall power for a lighter more playful version that I can ski all day.
I'm 6'1", 178lbs, 42 year old expert that skis truly all mountain. I have an extensive quiver and a gear freak. My style is described as technical and finesse but I charge very hard when skiing without all my family. Love moguls and trees of any size until my knee says no more.
Summary of the two skis is this. If swing weight isn't an issue for you, strong and healthy knees, you keep your skis on the ground all day, and just prefer more powerful skis then go Bonafide it's that good for a one ski quiver. If you are lighter, spend more time jumping around and trying to make your ski playful, prefer a little lighter weight ski to have on feet all weekend but still want unreal high end performance then Kabookie. I can't wait to ski mine in anything softer than I have skied it on.
