Salmon Dumonts

Anyone using the Salomon Dumonts?

I have a few questions about them:

1) are they made to be center mounted?
2) Do the edges hold up or have you had problems with them?
3) Do they delaminate easily?
4) What makes them different from any other salomon ski such as the SPK or Flyers... (other than the cool graphic)?

Thanks for your replies

PS: I tried the searchbar already so if you have a searchbar comment just shove it up your @$$
