Wheel trueing

I stand trueing wheels with a rear triangle mounted on 2x2 on 1/2 ply
b ut I'm looking down at the spoke/rim section caws the ply's too
short.
Maybe I'll raise it so the trueing section is at eye level.
Now, how to apply the screwdriver and sight the rim section ???
Sit down sighting across horizontally?
Or sight to the rim section directly in front of your face with the
nipple pointed directly at you?

seams lika awkward arm position no matter how you cut it ?
what did you have in mind for arm position, rim position?

The idea I work with is sighting across the rim to the trueing point
so I have a general idea of where we're going and where we came from,
circumferentially speaking.

DT has a nipple end that takes torque ??
