Jury's out. He's backseat, he skids a LOT of turns, and line shops all over the place. Sure, he can huck and point them down pillows, but that's not skiing, that's just leaping off of stuff with two sticks on your feet.
He's obviously using the fat skis as a crutch, so instead of waiting out his turns, he can wag them all around into whatever smeary mess he wants to make. He needs to switch to skinnier planks to keep himself honest, if for no other reason.
Get him in a good bumpline and we can see if he can transcend all of those bad and lazy habits and pull it together. Bring it back to the resort and work on some drills. Some work on falling leaf drills could do wonders for this guy. Bottom line is, he looks over-terrained and is compensating for the missing skill with an overhyped ski.
