Should I use crushed walnuts or pecans for my salmon dip?

I’ve made this forever. It’s a can of sockeye salmon, cream cheese, green onion, smoke sauce and lemon juice. Super simple and super good. The original recipe calls for crushing nuts really fine and rolling the dip in them and forming a ball.
I dropped the nut part years ago and just mix it up and serve it in a bowl.
We’ve been invited to a birthday party for one of Rick’s friends tomorrow. I want to take the dip
We’ll his wife is kind of uppity and the nuts give the dip a touch of elegance.
I think it originally called for walnuts but I like pecans better
What is you opinion?
