They're definitely on the more buttery end of the spectrum but in a very different way than something like the Blend.
The Blend has one very strongly defined "hinge" point in from of the boot that allows for insane nose butters but are actually relatively stiff in the tail which makes for decent stability on landings but overall a bit of an awkward ride for anything outside of the park/streets.
We use what we call a more intelligent or "deep" flex to the ski, meaning yup, it's one of the softest skis on the market, but when you're charging it doesn't feel soft and actually gives you really good grip/stability. The Vacation flexes mostly under your boot so when you're carving it actually contours to the snow and gives you super good hold while maintaining a loose, surfy sidecut. Then when you're slash and popping and playing because it hinges closer to your boot you have a lot more control and are actually able to lock into butters (with the ability to pop out of them) rather then flexing way out on the nose or tail where you aren't as centered.
In terms of the overall market for skis the Vacation is a pretty weird one, sorta wide, sorta soft, good for park, but also a "pow" ski in certain regions. It's actually the only ski I ride, I have one pair mounted at recommended (-4cm) with Shifts for touring and another mounted at -2cm with Pivots for park/normal day usage, definitely my favorite pair of skis I've ever been on for my style of skiing.
Remember we also offer a 100% money back guarantee! So you can buy the skis, ride them on your own mountain with your own bindings on your own time and if you're not completely stoked on them after a handful of days skiing you can literally send them back for a different size, model or your money back.
