Hey ski-ra. You might be interested in this somewhat similar thread. We're not too far apart in size, and we both like the Sultan 85 and seem to perceive its strengths and weaknesses similarly, so that's some level-setting anyway. A ski buddy who is our size just bought a pair of the Bushwackers in 166 from STP. Great deal. Personally I have a slight feeling that that ski might feel a bit short for me in that size. I haven't skied it, but have fondled them in the store and the rise, while low in magnitude, starts quite far back from the tip. Radius is on the longer side compared with the Sultans. With theses things in mind, likely they won't hook up on firm snow quite as emphatically as your Dynastars, but everything is a compromise.
Not sure why you say the LX 82 is "too narrow," when the 85mm Sultan seems not to be too narrow for you. 3mm is not much. However, the Kastle is not rockered, so that probably rules it out, based on your first post. Which brings us to the 2014 FX 84, which does have early rise. Why not the 166 in that ski? Dough, perhaps.
When I was asking my very similar question, I got a lot of suggestions for the Rev 85. Not sure I understand why you're ruling that out. You think you're between sizes? Again, you're on a 165. Why not the 163 Rev? 2cm is nothing. And if you think it's not floaty enough, there is the Rev 90.
What about the Outland 87? Seems like a natural segue from the Sultan.
Finally, based on what I've heard, I would not rule out the Crimson. Apparently this ski has undergone a personality change. When I tried it a few years ago it verged on the "wide carver" genre, but supposedly it's been softened and rockered twice since then and feels looser.
