The only ones i've tried are the Al Dentes (Tried them a weekend, i do not own them), so i cant really compare any of them..
The Al Dente is a super sick ski, and it fits what you want perfectly. Its a park ski, its wide, and most of all, its soft.
I know people who own this ski, and has been skiing them all season, and none of them has been complaining about the edges.
If you have the money, go for the Al Dente, if you're trying to save some money, i'd consider the Halo 2 (Armada). I own this ski and i've been using them all season. I've had no problems with durability. They are also a wide and soft park ski.
