On the 36 spoked wheel I noticed that little quarter turns and half turns got me where I wanted to be; on this one, it seemed like quarter and half turns did absolutely nothing.
I am going to take this wheel to the shop to get it trued. In the meantime, are radially spoked wheels really harder to true than cross-spoked wheels? Or does it just have to do the number of spokes?
It's probably spoke windup.
Given market demands for low weight. more expensive wheels tend to have lighter spokes and alloy nipples which stick when not properly lubricated.
Contemporary rims tend to be deeper allowing higher tension. Lower spoke counts also call for higher tension. This increases windup.
Using anti-seize on the spoke threads at 120-130kgf you can get 1/4 turn of windup in a 2.0/1.5mm butted spoke before tension changes, and with problems even a half turn may not be enough.
Add a drop of oil on the hub side of each nipple and socket to reduce friction. You'll get less windup, it'll be more comfortable, and you won't bend aluminum nipples that aren't too frozen.
Put a tape flag on a representative spoke (I like the first (and second for rear wheels) after the valve hole) or Sharpie dots all around to see what's happening with windup. Measure your quarter or half turn from where the windup stops and completely undo it.
