Replying to Line Outline or SFB

Hi, I am seeking some advice regarding which ski would be best. I currently own the SFB and the Sakana. At the moment I can get a good deal on the Outline and have a potential buyer for the SFB, so I will not have to pay any extra if I decide to swap.

My thought is that the Sakana and SFB might be a bit similar, and if I get the Outline I have a broader range to ski on. The Outline might not be as versatile as the SFB, but maybe the sakanas can fill the gap?

I have Atomic Shifts on the SFBs and had them planed for a trip or two into the backcountry each season. How will the Outline be as a backcountry ski? And is it mostly a ski for the big occasions when the snow is perfect?

Any thoughts?
