I was lucky enough to demo some of these on a good spring powder day. This was actually the first time I was able to ski some fat skis in the powder and I was honestly blown away. Nothing compares to fat skis in fresh powder.
After a few runs I got used to the fact that you can ski through the crud like it was groomed. At first I was tense through the cruddy steeps like I am on my normal skis, but once I got used to them I relaxed and sped up considerably. I like to make long fast GS turns down pretty much everything and these excelled in cutting through the bumps allowing me to go as fast as I wanted.

I wasn't able to hit any groomed trails but I did ski through some packed down snow and I wasn't super impressed. For me they handled OK on the packed snow, about as well as I was expecting. I don't think they are really made for carving up corduroy though so it's not a deal breaker.

Pretty much the perfect backpack for my situation. It is not the biggest bag available but I can still get in several fat texts books, a few notebooks and a laptop. Before I had this bag I would end up with a backpack on my back and several books in my arms which was a pain. Now its just one bag with everything.

The straps, and the bag in general, are comfortable but I would recommend putting your largest book in the rear of the bag due to the large pouch positioning some smaller books low on the back. My one tiny complaint is the number of pockets. It has a very large front pocket, the main bag area, then one small pocket on top for random crap. 3 pockets is probably enough, I just wish I had maybe one more for more random crap because I am a messy disorganized guy. I guess a specific spot within the bag for a laptop would be nice but its absence doesn't bug me enough to care.

Super great bag.

I have been skiing some short boards for the past several years so I demoed some 185s . I wasn't really digging them for the first few runs because I was not really used to the length and weight compared to short skis, they got better after a few. They don't really lay down easy carves on regular groomers.
I was able to get them into some steeps and they handled well.
It wasn't till I swapped skis with my bud that I noticed the real difference these make in the crud. I can't compare them with the other Dynastar Models but these cut through very well. Took the same run twice on different skis and level of speed I was comfortable was much greater on these skis.
I wouldn't recommend these as an all mountain ski but they would work very well on steeps, in the powder, and railing through crud. I like to ski very fast and they performed well.
