Replying to Powder ski recommendations

Alright, my dad really wants a powder ski and is pretty flexible with his budget. Basicly, he struggles in crud and powder with the skis he has now (fischer big stix), and wants something pretty fat. He's an expert skier, 5'10" 170 lbs. He's been reading my Freeskier buyers guide and likes the reviews of 4frnt Vcts, and volkl gotamas. Don't worry about suggesting shit that you wouldn't expect a dad to ride (armadas or 4frnts) cuz itd be cool if he got them so i could have em when he's not skiing. Any recommendations would be super duper.
