Overall I would rate this ski as an 8-8.5 because they are a very durable ski that preforms well. The only quarrels I have with them is that they are ugly, a little heavy, and the standard mounting position is a little far back. If you can find yourself a pair, pick them up. They'll definitely hold up, and if you get a bad pair, volkl will definitely warranty them for you.
This ski is great on hardpack and crud and on the lighter powder days. It holds an edge extremely well and because of it's flex, it is extremely stable. Its probably the best carving twin tip I've owned.
You can definitely ski powder with these sticks. They will ski pretty much all but the deepest powder. I've found cliff hucks are harder to land on these because they are a midfat and tend to sink a little.
I can't say much for the park skiing attributes of this ski. I have taken them off some 20-30 foot tables and they seem to be alright, but spinning is a little tougher due to the weight attributes of this ski. The swing weight seems to be on the heavier side. Mine haven't touched rails because i want to keep them sharp for carving.
Well, the graphics definitely suck on the model I have, the 185. The gray not awe inspiring but thats really not the point of this ski. The newer versions seem to be better in the graphics department. The top sheet on this model is a rough, and pretty much feels like sand-paper. This is great for grab, but sucks because I was unable to cover the ski with stickers and make it more attractive looking.
Overall I am very happy with my choice. They are a quality skis, a Volkl trademark. Got them for 600 mounted, so not the best deal, but still pretty good.
The Karma is a fairly stiff ski, which has its ups and down. On the plus side it is extremely stable on hard pack and crud, however it is somewhat heavy due to the metal sheet that is integrated into the ski.
These skis are bomber. There have been no signs of delam in over 2 years. The top sheet has a few nicks in it, but overall the ski has held up extremely well.
