First a little about me. I've skid 40 days thus far this year, mostly up in tahoe, but also 6 days at Jackson Hole. I've done a little bit of racing, but only 1 race this year. Last year I skid over 50 days. Powder is by far my favorite condition, and I love small (less than 20 ft) cliffs.
These skis are amazing. They actually carve well on groomers (better than my rather worn out Salamon Equip 2V GS skis). They are very forgiving, especially on landings. They are however a lot heavier then many freeride skis, but they also seem a bit stiffer, which makes them great in crud and on groomers.
I bought them as powder skis, living in CA, I didn't feel I needed more than 90 underfoot, and even after getting 5 days of awesome powder in Jackson Hole, I haven't changed my opinion, they worked awesome. I also use them as my park ski as while I own 6 pairs of skis (AT, 2xslalom, GS, and rock skis) these are my only twintips. Basically, if I don't want to do slalom, I use these skis, for ripping groomers, park, and powder. They are just that amazing.
I broke the original bindings (Mojo 15) doing a 360 at Kirkwood, but Head replaced the bindings without any issues. They unfortunately didn't have the same binding so I'm now running on freeflex 15s (it was a powder day and I didn't want to wait for them to be shipped). But to me breaking the bindings just showed me how great Head is, at least working through Head North in Truckee.
