Tom, I've never fished for them, but have had a few folks get jigs from me and they said they were for Walleye.
I don't like the idea of standardizing a hook size per weight, but understand why, since costs have to be controlled.
With some exceptions I've tended to go a little larger with hooks for bass, and seems that should work fine for Walleye's too. So, for a 1/8 oz hair jig I like a 2/0 or 3/0 hook, but have used smaller & larger.
For plastics, I also like a slightly bigger hook, and have compared some of the mass produced and it really depends on the plastics your using. For example, I like the Zoom Fat Albert grubs, and a 3/0 hook gives more bite, without needing the plastic to compress a lot.
Folks say, they'll hang a lot, and in some places they will, but so will smaller hooks.
There's no single answer IMO, and much of this is personal preferences. If you're buying premium hooks, as you go larger the prices usually go up, so that might limit the size too, but for my fishing, 2/0 & 3/0 has been a good size for the lighter jigs, unless I'm making them to use with very small plastics or for tying smaller hair jigs.
BTW, I very much like the Mustad 32746 hooks for these types of jigs.
These jigs are some I like a lot for grubs & other baits, made from a modified wacky weight mold. All have 3/0 Mustad 32746 hooks in them.
