Super small hook and a split shot, pretty universal, with quality bait, I’m not sure you “need” much.
Honestly I got a whole box full of stuff, I find my Ratso’s and Genz worm are my go to lures, Found a Genz worm kit at I think Gander for cheap, had a bunch of lures for under $20. Those work nicely for me when the bite is tough.
I think I could do all my ice fishing with those three, and do just fine.
I would like to add some spoons for the ‘eyes, I think you could put together a nice little box for $50. I guess I think of ice stuff more as things I could use in summer, versus summer stuff I could use on the ice.
I did have a little luck on some tube jigs, and some fly fishing flies in winter, otherwise I don’t use much of my summer stuff. I caught some fish, but it didn’t seem to really make my catching any better.
