Replying to Icelantic Da'nollie

Does anyone know about icelantic da'nollies ? They look like a sweet ski! The problem is I dont know much about them? I am 5'5" 125 lbs. I ski 80% park 20% mountain. I ski at park city so I want it to be sturdy enough to hit larger jumps 30-50 feet, but still be playful enough to do small butters here and there. I'm probably going to get 170cm Length. How true to size are they? And final question is, post any edits with them. Thanks
