Yeah, just buy the Navigator 80.
I'm 179 cm tall and 179 lbs. I've been skiing the 172 cm Navigator 80 a bunch with our kiddos and love them. We've been skiing mostly blue bumps, trees, and groomers, along with a handful of black bumps and trees at Copper Mountain. They've been a great ski on all that terrain. Some proud dad pics:

I know the price the Navigator 80 makes them feel like they are not a real ski. Don't worry, they are.
They ski like an easy turning advanced/expert ski with a nice even flex that love short turns. They make skiing bumps easy and the bit of rocker makes them easy to smear and ski switch. Great, fun ski, regardless of the price.
Not to mention @SkiEssentials has the the Navigator 80 for $399 with bindings and $299 without. And that’s before the PugSki 10% discount.
