I don't see Miles getting launched over the handle bars or struggling with those types of fore-aft issues that would be the case if the snow were sticky. I can't think of any other reason why Miles would call it "grabby" as I see plenty of soft slush swishing away from the tails of his skis. I don't mean that as a criticism of the skiing, just an observation about the snow.
Sharper edges? No.
Miles didn't ask for MA, but he's going to end up getting it anyway I presume. The main reason I think some PMTS skiers have posted their ski videos here has not been to get MA. In fact, most of them are not even open to hearing very much (if anything) that is not coming from a PMTS certified coach. That being said, others might benefit from the MA.
The first thing I notice Miles is that your feet are a bit glued together. I would expect to see much better foot independence and vertical separation. I'm not saying wide stance, but I would just like to see your feet working more independently.
Secondly, get out of the backseat.
Otherwise, glad to see you're out skiing late in the season and looks like you're having fun.
