bieberhole69.I haven't skied the sfb but I love my kung fujas. Do well on groomers, and tear through ~3-5 inches of fresh. The only time I've skied them in more than that was around 12" and really heavy, and with a little bit of speed I was really surprised by how well they did. They do alright on ice, my guess is a little better than the sfb, but obviously a narrower ski would be preferable.
For length, I'm 6'2" 165 lbs and I felt like the 189 would be a little too much ski so I went with the 179. Works great except for when I'm going really fast, but with your size they'd be perfect.
I ride the SFB and can say that almost all of this applies to them as well. I had a couple chances to try a pal's fujas and they ski very similarly. I found the Fujas to float just a tad better than the sfb, but I think the bacon is just a tad more playful. For reference I am 6'2", 180lbs. My Bacons are mounted dead center and are 184's. The Fujas were (i think) the 179 mounted around -2. Dimension wise they are pretty close in shape, my bacons feel almost exactly the same swith as they do forward.
Long days and pleasant nights.
