Big Moose Mt / ME - Cat Skiing ?

Friends want me to join them on the Cat Ski trails at Big Moose this Saturday. Curious who’s been and what you might compare the cat trails to ? Ex— I don’t do Castle Rock chair at Sugarbush anymore —- my knees can’t take it 🫠is it like that ? Even kitzbuehel and Jet at Jay — I’m passing on those. Thx for any input.
