Kung Fujas or Sir Francis Bacon?

Bump. It might be helpful to include where I will be skiing. I'm going to whistler in January and do most of my skiing in Colorado and the PNW. Thanks.

tough choice but I say 84 bacon.

i love my bacons so much fun

Definitely not Fujas then, they are an all-mountain ski, if you ski that much backcountry, which I doubt then even the Bacon seems needlessly versatile.
When you say 'off piste' do you mean sidestashes/slack-country, lift accessed? Or do you mean sledding/touring in to the back country, I'm guessing the former? Do you jib in the pow/ski pow jumps? If not why pick such jibby skis? I personally ride (/rode last season anyway) the Bacons but I ski maybe 90-95% park on them, they are so versatile they can be a fat park ski, a backcountry jump ski, turn on groomed well enough and still float when it snows. I wouldn't call them a pow ski though. The mount is too forward and there isn't quite enough rocker to fully compensate that IMO.
If you want a jibby pow ski that holds its own on groomers, I'd go for the Opus. If you want a pow ski but don't jib much, I'd go for something with more tip rocker and less tail rocker, a more directional shape.

What I meant with my description is I ski lift-accessed runs in-bounds and hike-to-terrain, not true backcountry.  I end up skiing groomers just to get from place to place on the mountain or because there is no fresh snow.  Since I don't live near the mountains anymore, conditions can be hit or miss when I ski, so I want a ski that can handle groomers (even though it's not my favorite type of skiing). The main reason I have dialed in on the SFB is I do drop some smaller cliffs and want to get more into spins, jumps, and skiing switch.  I have heard the bacons are killer in the trees, which is my favorite type of skiing.  I do feel that I am looking for an all-mountain ski, but one that is more powder-oriented.  I don't really want a true pow ski because I can't guarantee I will be skiing pow, and don't want to have to travel with two pairs of skis. 

I lived in Colorado for two years recently and really regret not demoing more sks.  As a result, I don't really know what my preference is in a ski.  So now I hve to rely on reviews and awesome forums like this.  I currently ski the 176 atomic snoop; it has treated me well, but I feel that it is fairly boring and not great at any one thing.  Would you recommend a different ski?

Also, skiing the 184 and me not being that big, I am hoping it doesn't ski as soft for me as it does for others. 

From what you've said, focusing on line for a second the opus seems like a good choice but i would look into the influence 115. Its very similar to the opus but is more focussed on the quality of riding forwards than the opus which is a compromise of forward for the ease of switch. Thats not to say the influence wont ride switch it just wont be as easy as the opus. The influence has a stance a fair bit further back (57mm more, i wouldnt mount this far back though, maybe -4) and has more camber & longer running length for when it gets steep an tech or on piste. The influence is stiffer aswell. Im not saying to pick the influence 115 its just worth considering for a more steeps oriented ski than the more powder oriented opus.

Bacon or Opus could be good from Line or even the Influence but they are more serious and in my opinion less fun (by which i mean playful, not that they can't be fun in the right conditions).
Personally I can't really fault the Bacon as a 1 ski quiver, they carve well, they are pretty light in the air not too soft but still buttery. I'm around your size and a bit lighter but I was prioritizing spinning and rails so I had centre mounted 178s. I can't see traditionally mounted 184s (actually about 181cm) being anything but great for you in pow. That said the Opus is a very similar ski, it's a bit better in pow and a bit slower on groomed but there is a lot of overlap. Bacons really are the most versatile ski I've been on though, my only criticism and possible reason not to make them my bigger ski from Line again this year was the swing weight on fast rail tricks but that won't affect you at all.

Op If you can afford it maybe go ON3P. Two skis in their line up too look at is                                  Jeronimo (186 is 132/101/125)
or Jeffery (186 is 136/110/128).
Just throwing a suggestion out there for options. Jeronimo would be comparable to SFB specs.

I'd definitely go with the bacons, because in the bumps the kung fujas may seem kinda wide but I also prefer the flex of the bacons over the fujas. They'll be more fun/playful/lively which will be nice with your weight , the fujas will feel pretty damp which you may not enjoy as much
