Pros: Quick, Responsive, Easy to use, Forgiving (at lower speeds)
Cons: Has a speed limit, Needs supervision
The (2007-2008) Dynastar Contact "Limited Edition" (LTD) was the top-end model in the Dynastar Contact line in 2007-2008. (The 2008-2009 Dynastar Contact 10 appears to be nearly identical to this ski.) With a 72mm waist, 16m radius (@178cm), and a titanal layer, it can shred anything from solid ice to a foot of powder without batting an eye.
I demoed a number of different skis before settling on these. What I liked most about the Contacts was their extremely good responsiveness -- whatever you tell them to do, they do, and they do it fast. They also hold an edge extremely well on hard snow surfaces (which happen from time to time here in New England), and have enough mass to slice through crud or mixed snow conditions without being tossed around. They are also forgiving of technical flaws while still being capable of making extremely dynamic turns, making them a great learning ski for an intermediate skier looking to improve their carving. This season (2008-2009) I picked up a part-time job as a ski instructor, and have found these to be great teaching skis. It's easy to demo any technique from wedge turns up to parallel on them at any speed, and they've held up extremely well to various forms of abuse.
Having had more experience with them this year, I have found a few flaws. The main problem is that they're not race skis -- at very high speeds they get jittery, especially if you are in the back seat. If you can keep up with them, you can push them pretty far, but I have a lot of trouble doing that on steeper pitches. Basically, the faster you are going, the more their responsiveness can start to become a liability. If you're not right on top of the skis and constantly driving them in the right direction, they will not behave nicely at high speeds. And, obviously, they are not really built for skiing deep powder -- although I did get to use them a couple times in 6-12" of fresh snow and they did just fine. They also have not really improved my mogul skiing, although I'm so bad at moguls that I'm pretty sure it has nothing to do with the skis at this point.
If you are an intermediate to advanced skier looking for a versatile, all-around frontside ski, and you want something that's more forgiving than a race ski but still very responsive, try the Dynastar Contact LTD.
