To be clear, this is all relative to what we're used to skiing on, but the FX94 is a superb ski, and easy to pilot as long as you are willing to tell it what to do next. But the basic design, including a flat tail and very mild early rise, plus those two sheets of .4 mm titanal ≠ playful.
Whereby there are a bunch of skis in the 90-100 range that would be called playful by most, even at your size. They would tend to have pronounced early rise, typically at both ends, a fairly deep sidecut, and not be quite as stiff as the FX, but not styrofoam skis either. If you love the Prophet 100, then I'd think you should demo a Supernatural 100. Bit stiffer, apparently, than the Prophet or the Supernatural 92, but still playful. Or I'd bet the Atomic Alibi - similar design, including early rise tips and tails, and a titanal spine - would please. Likely a bit beefier than the Supernaturals still but that rocker thing, y'know.
Some of this is also about terrain. A playful ski will be easier to swivel through trees and bumps, but may require more concentration at speed in chop. So your list of criteria is kinda broad: Opening it up on the frontside, but also trees, powder etc. Maybe it would help if you prioritized...
Along those lines, keep in mind that you don't need a lot of overlap with the S7 in terms of powder. It's very maneuverable, and easy to handle in soft stuff, even a few inches. So perhaps you want something that's a better complement than another playful/finesse ski only 16 mm narrower? Personally, I'd be looking at skis in the high 80's that can crush frontside crud, firm, and bumps. The Brahma, last year's Steadfast, or the E88 seem more in the ballpark.
