I had a chance to demo the 2013 Head Rev at Mt. Rose last Tuesday and thought you might be interested in my impressions. I don't have all the information to offer a complete review of this product so I didn't post in Member Ski Reviews.
I'm 5'9", 195 lbs., level 8-9 skier and the conditions were light chopped up powder, soft bumps and some groomed. The ski was a traditional cambered 181cm Head Rev but I don't have the tip, tail, and waist #s. I used this ski for 4 or 5 runs and I was very impressed. My current powder boards are Volkl Mantras in a 184cm from the 1st year production. Admittedly, an older powder ski, but I was still surprised at how much improvement had been made in the last 8 years. The Head Revs are about 10 mm wider throughout the entire length than the Mantras, but felt like they had more sidecut too. They were predictably fun and easy to turn in the cut up powder (about 15") though the snow was light enough that I can't comment on how well they would work in heavier crud. The thing that impressed me most though, was how agile they were in the soft bumps and groomed runs. They were only slightly less quick edge to edge than my frontside boards, (Volkl AC3) and extremely easy to initiate. Solid carves at high speed and very damp. In short, I think Head has built another great all mountain ski.
