Going for my first Brown opener on the river next Saturday , any suggestions to add to the box?

I’ve never fished for trout on the river before , I have my chest pack with extra line, my tools and my waders all ready. I think I have all the necessities but if there’s any suggestions that would be great!

The spinners are all 0’s 1’s and 2’s and the spoons are 1/4 ounce and smaller I believe
