You can use standard or ice marketed lines, 4lb-6lb. If it’s really about this one trip than setting up for a season then many choices will be just fine.
The group I go with uses all kinds. Some are really picky, one guy just uses what’s handy from summer, and one guy has braid on one of his rods.
We haven’t see a huge difference in our group. I’m the picky one in the group. That said I’m setting my rods up for particular presentations for the whole season. I’m matching line to rod weight: 4# ice mono(deadstick), 4# Pline(1/8th or lighter), 5# pline(1/8th-1/4 if I can find it), and leave the braid rod at home.
With a little patience you can land pretty much any walleye with this line. Just check your drag in the morning before cocktails start
