Replying to Ski Setup after ACL/Meniscus Surgery?

I'm getting back on the snow after a 2 year recovery post-op. I ski slopestyle and urban and I don't know if I should change my setup for something safer. Planning on picking up some Vishnu Keys but I don't know if I should get something skinnier/stiffer. I am also used to cranking my dins up to a 9 for nollies and whatnot but I don't know if it would be safer to lower that. Any recommendations on skis/settings?
