I tried my Hoks 145 this past weekend on local MSP terrain in deep, soft, mushy, snow. They performed well with good glide, flotation, and traction.
David Chanault described them perfectly in his Bedrock and Paradox blog posts last winter.
They have a very specific use where you would take snowshoes and not skis. I agree with David in that they are more efficient on traversing tight rolling terrain than snowshoes.
They have the flotation you would expect from a short "Big-Fat" alpine touring powder ski with 110 mm underfoot. However, at least for me, they are not for skiing downhill in the normal parallel or telemark fashion.
The flex is too soft for me at 180 lbs. Even when I distributed my weight evenly over the skis, I still bottomed out the climbing skin on each ski.
So I went back and watched the You Tube videos. I noticed that the users were not "skiing" downhill, but were "running" down the slopes.
The "running" downhill technique is probably more efficient and fun than running downhill with snowshoes.
My Universal Trace binding worked fine.
In short, the Hoks do a good all-around job for their light weight(about 3 lbs each).
I look forward to taking them to the SHT in March, unless I get side-tracked to the BWCA.
P.S. I noticed that Altai skis has a new and different ski at 147 cm for the 2012-2013 season. The ski is stiffer than the Hok 145s. Apparently, it overcomes the problems with too much flex found in the Hok 145s.
