At the time of writing (11/3/15) these are my favorite park skis I've ever ridden. Sounds like a big claim but you have to factor in that, as a rule, I don't actually like dedicated park skis. I prefer the feel of a surfier wider ski, with lots of rocker and medium to softer flex.
I have actually skied a lot of park skis over the years at tests etc but none has really blown me away. Until now my two favourites have been the Alpha X (tenuously a park ski), and the Domain. The Antidote skis a bit like a lovechild of the two.
Superficially, it's closest to the Alpha X (and the Amplid Rockwell from which the Antidote was derived) but has the jibby playfulness of the Domain. It takes the 5 point sidecut, extends the tip/tail rocker and makes the whole lot symmetrical. It's also a few mm narrower at the waist for extra speed edge to edge and the flex is softer in the tip and tail sections. The result is quite frankly close to the perfect rail/jib ski.
They essentially ski like a skinny version of the mid-fats I love to ride day to day. The flex is still what I'd call medium in the tip/tail and solid underfoot. But there is a lot of rocker so the Antidote is seriously easy to butter. They are also extremely light to spin thanks to the symmetrical shape/5cut and poppy thanks to a combo of camber underfoot, carbon stringers (along the base not the topsheet so they actually do something) and the flex. The solid flex also meant I never wheelied out on landings, but if you got really backseat you would. They aren't a dedicated jump ski but they do hold their own fine.
Around the mountain they are also surprisingly good. Not too much chatter while skiing around happy enough at mortal speeds. The generous rocker helps deal with crud and mixed snow conditions though in reality, 90mm isn't enough to keep things really stable. For me the sidecut is a little on the short side, I prefer to carve around lazily than make short whippy turns but it's not a major issue and it does make them even quicker in tight spots.
From what I can tell in the 3 days I've ridden them, the skis are extremely well made. The topsheets are bomber, I've seen no significant damage so far and I can't see any evidence of edge gaps or other hallmarks of a below par build. The bases are 'sintruded' which as far as I can tell is basically a high grade extruded base. They aren't however noticeably slow, like say the Domain or Afterbang so I don't think that will cause many people an issue. I couldn't feel a difference from a normal recreational level sintered base in terms of speed.
The edges aren't the fattest however, though there is some shock absorption tech and the abuse base technology to help prolong the ski's lifespan. Honestly, I can't say if it works, I've only had 3 days but Amplid have a good reputation for ski life despite not having the biggest edges.
Essentially if you like the way a mid-fat ski rides but want something easier to spin fast in the park, these are your babies. I don't do much in the way of spinny tricks but these are the first park skis I've ridden that really gelled with the way I like to ski park, and make it feel fun/easy and not like I'm forcing the skis. I'm not 100% converted, I still feel more comfortable on a 100mm platform and I probably always will. But these are the first park skis I've tried that I feel wouldn't make me enjoy skiing less than the midfats I generally ski.
Just to start out i'm going to write this as non biased as possible. The ski is super super fun! soft in the tip and tails and a mid-flex underfoot. its pretty rockered and rides accordingly thus its forgiving and fun to butter and press on. That being said it does take away from stability. All around Id say its a 9/10, just about perfect for me in park!
