Hey Skiking4. If a ski like the Bonafide is off your list (and at your height and weight and stated preference for something snappy, fun and maneuverable in tight spaces it should be off your list), then you should also cross the Influence 105 off the list as well. As I have said elsewhere, the Influence 105 is a great ski, I loved it both times I rode it (fwiw), but it is more of a damp big mountain charger. Not a comparable ski to the Bacon. More like a ski you'd compare to Bonafide, Cochise, Ritual, E98, Cham 107 to name a few.
The Bacon is a whole different ballgame. Rode a buddy's Bacon a couple of mornings ago and was impressed. Conditions were +/-8" of blower in steep trees with smaller stashes of powder, and soft lumps of snow on the sides of the groomers. The Bacon is super light feeling, very quick, fun and jibby. It has a reasonably traditional shape, however, so on edge it doesn't feel too clowny or ski bladeish on the groomers. I don't think that it is stout enough for a full-on hard pack day (for me), but it is excellent on soft groomers (quick and fun), when groomers are transport to the main event - my buddy and I both outweigh you by a ton and we were both pushing the Bacons hard through down this groomer over a series of rollers that returned us to the chair (and back to the pow stash). Soft bumps, tight trees, loose low angle trees in a few inches of blower they were great. As advertised, it skis pretty short. I was on the 184 and found that perfect for me, but I am 5'11, 185#. At your size, the 177 would be perfect for you.
Of course, in powder the Bacon was dynamite. Nice float, ability to surf and slarve. I didn't feel like it gave up much over a fatter powder ski - and the return was a way snappier ski, better carving ski in lower snow, skied off conditions. I have another buddy in the market for a fatter ski right now, about your size, who loves a quick high energy ski and I immediately thought that the Bacon should be on his demo list - at his/your weight the Bacons would plenty of float for deep days and would be way more useful on more ski days than something fatter.
If you want a wider, lightweight, high energy ski that will be great on soft snow, soft bumps, tight trees in soft snow and is modern and loose enough to migrate to the park, the Bacon kills it - you'll love it. Just save your Volkls for ice/full-on hardpack days, which would not likely be the Bacons' best venue - workable if tuned and if you have good technique, but save them for the fun stuff where they will shine. My perspective is very western-oriented, but I could see the bacon as a great eastern powder ski (especially for a lighter skier with some park interest).
Plus, they are reasonably easy on the pocketbook - especially in late Feb/March.
Only word of caution - the Bacon is not the ski for the skier who likes a damp, powerful, metal laminate feel (the skier who would be looking at the Influence 105, for example). It isn't that the Bacon isn't enough ski or that it is unstable when sized correctly - it just falls on the lightweight, snappy, quick side of things.
Don't know anything about the 4FRNTs so I can't comment there. If you thinking about the Bacon, another ski to consider that I have been on would be the Nordica Soul Rider. ~10mm more narrow and a little more firm underfoot, so a little more solid feeling on groomers, but similar fun factor. All mountain twin tip, so you can take to the park and back, like the Bacons.
At 17 years old, and your size, you'd love the Bacons (as long as you have something to pair them with for firm days out east). Pick some up, don't look back and report back on the cool stuff you are doing with them. Don't overthink it. Have fun.
