The ANT's could be exactly what you described. It would be a toss up between ARV's and ANT's for me.
The ANT's are a stiff ski with a long turning radius (25+ i believe). They'll definitely plow through crud, but since their stiff, they won't be very forgiving. At 25m you'll usually be flossing and it'll be a bit of work to make em your bitch. The reward will be a charger though. If your main goal is to haul balls from A to B its probably your choice.
The arv's shorter turning radius and flex will lend to a looser, little more playful ski. It will still hold its own charging the mountain, but it'll be more versatile as well. The ARV's will be about 10mm skinier too. Considering you already have opus's it could be good diversity. I'd much rather take ARV's on a hot lap through the park than ANT's but if you're just taking pipe laps it may not be as big of a toss up.
in sparknotes, i'd say ANT for a stiff, long carve charger you're willing to be on top of or ARV if you're looking for a little more versatility out of an inbounds ski.
