Replying to Skis For My Old Man?

Hey NS,

I'm in need of some advice... again.

So here's a little info for y'all:
My dad is an absolute ripper, has been skiing his whole life, and is so much fun to ski with. (Yeah, I still ski with my dad sometimes, he's fucking great.) But, this past year, he's been having a lot of trouble with his knee/calf. Long story short, he's getting old and crotchety, which is terrifying enough in itself, but even more so when we realized he wouldn't be able to ski anymore if he didn't get it together. So, right now, he's trying to do just that and I've suggested that, in order to help, he needs to get off of those ancient titanium race skis and onto something a little less... race-y.

So humans, here is my question, should you choose to answer it:
Do you know of any light skis that turn easy but still pack enough punch to satisfy an old dude (and by old dude I mean slightly narrow-minded dude)? He lives on the east coast and weighs around 165lbs, fyi. Would be skiing all-mtn/groomers with the occasional bumps or pow run. He's not super aggressive, but if they don't carve well I'll never hear the end of it.

Massive thanks! Peace
