True story: Last year I was looking to upgrade my BC setup to something new and light weight. I also wanted to dip my toes into the race scene, and I wanted 1 pair of skis that was adequate for both disciplines. I found the Skimo.co website through an interview that Jason did on Skintrack.com. I knew nothing of these type of skis and did not even recognize most of the brands that Skimo was selling. After working through the site, I wrote Jason to ask for help and inquire about the Cirrus skis which had a great weight, width, and price. He emailed that if I found these skis then I did not need his help.
These climb like race skis and ski like 90 underfoot. They are the best skis I have owned. Even now that I have a pair of race skis (Hagan x-races) I would not hesitate to jump into a race with these. Similarly I do not hesitate to bring these out on an epic powder days. They are just that good.
I would say that they have a medium radius sidecut. In general my style favors short turns...If I am going to hike a few hours for untracked powder I want to make as many turns as possible. These ski's natural instinct is towards slightly longer, faster turns. However, without too much effort they will turn as much as often as I want and need. Otherwise, they simply haul. They are equally comfortable and maneurverable in tight rock-hard couloirs, wide open powder-runs, mogul fields, and groomers. They do well in just about every condition and at any speed.
These are the first rockered skis I have owned. The squared, rockered tip floats through and over conditions and obstacles with the relative ease of a much wider ski. This may be why these ski much "bigger" than they really are. The rocker does decrease the effective running length and edge/snow contact and this takes a bit getting used to. For these reasons the ski seems to ski wider and slightly shorter than you would expect. If you are good enough skier or are accustomed to a rocker it won't take long to find the right balance and sweet spot. Like any light weight ski, there is a bit more deflection compared to a heavy ski. But these skied so well, I was used to them after 1-2 runs. There was almost no learning curve. With any ski this light, your legs will be fresher and you will want to make more runs...also a true story.
I have put these through the ringer. Lots of rocks!! Other than some scratches, the base and edges have held up gloriously. I actually think the lack of mass has something to do with this. Rather than plowing into rocks, these tend to glance off.
As I get more accustomed to this new scene of racing and light-weight touring, I find that people are always comparing notes. These set-ups are expensive investments, and we can't try every ski and boot. I heard a guy say that he has one of the lightest pair of race skis...and they ski like the lightest pair of race skis (aka, not very well). If you are like me, you are probably comparing every combination of skis on the Skimo.co site and looking at all the weight/width ratios....likely late at night, after work, and much to the ire of your spouse/partner. There are probably skis with better "ratios." There may be skis which ski as well. But I doubt there are skis that ski much better or are as versatile. I cannot feel a huge difference in weight (just over 200gms) between these skis and my race skis when skinning. There is a difference, but not much. Similarly, I cannot feel a huge difference between these and my 100 under foot powder boards when blasting through bottom-less blower pow.. Sure, each ski will excel in the correct condition or situation. For light weight touring, racing, or ski mountaineering, when one needs and wants to be fast and light, and also needs to deal with any condition, these skis don't disappoint.
