K2 makes some of the dampest freeride boards on the market harshmellow is for realz. Jones and Rossi are both not worth the money. They are less stable and damp than you want if you're maching. I'm curious as to your problem with Flow. They do not make a board I would not personally ride. Even their pricepoint board would make for a fun softer powder killer in a bigger size. Flow has a huge Euro following so their sidecuts are freakin dialed.
Maybe also look into the Nitro Blacklight Gullwing. Gullwing is one of the best camber designs in my experience. It has a characteristic to stiffen up a board when on edge but when you need it to flex and give, it does. It really lets you rail a euro carve without having to man handle a stiffer board around. Super quick edge to edge too
That thing I do to escape the world and have fun with my friend
