Board Setup For Bowl Skating [41YO]

There's a bowl near my house and I've been trying to learn to ride it. I can drop in and do an ok frontside carve.

I'm wondering how I can improve my board setup. I get a bit of wobble as they are now, but if I tighten them, carving is hard and I end up tick tacking.

8.25" deck (14.25" wheelbase I think)
Ace AF-1 hollow 33s
Bones hardcore medium bushing

Any tips?
