Trolley Wire height for Paulzmay contact wire 20

I have several routes which use the PCC Non real trolleys by TUME.

I use the Poles by Paulzmay (one example kuid<134105:34201>. He has a whole series of poles.

PaulzMay also has a contact wire 20, kuid<134105:3120> which I think was specifically designed for use with these poles.

My problem is that the wire is a little bit higher than the pole attachment and also higher than the trolley pole of the PCC non-real trolleys. There is a gap between the trolley pole and the wire.

My question is whether there is a way to adjust the height of the wire.

In some of my routes I use the Strabgleis track by rw1hh, kuid<2:69084:38005:1. This track has the overhead wire built in. The height of this wire is exactly right and work with the poles by Paulzmay. There is no gap between the trolley pole and the overhead wire.
 
You can adjust the height of the spline like any other by applying whatever height you need to at each and every spline point.
 
Below is a portion of the config file for "contact wire 20". I was hoping that the line "adjust height to ground offset" would do the trick. But changing the value doesn't seem to have any effect. Altering the "use superelevation" line didn't make any difference either.

In the original DLS version of the asset the mesh length was set to 20, but this didn't look very good on the curves. I changed the value to 2 and now the curves are very smooth.

track
{
mesh-length 2
adjust-cross-section-to-ground 0
adjust-height-to-ground-offset 0
coordinate-transformation "spline"
use-superelevation 0

track-lod-tree
{
mesh "default"
 
I just tried that myself and came here to post that those values didn't work probably because they're related to track and not a spline even though both are considered track. The mesh-length tag setting sounds like a good idea, but that may impact performance just like the old track 2m segmented used to.
 
I think I have a workable solution. It requires using the Classic Surveyor Mode which shows the big circles for the spline ends.

I lay the track. Then I use the contact wire 20 and overlay its spline points directly over the track spline points. This allows the contact wire to exactly follow the track curvature. Also, this gives the contact wire the same relative height as the track. I then adjust the height of contact wire 20 to -0.1 for all the splines. This gives me the correct relative height of the contact wire. Using the mesh length of 2 gives the contact wire the same curvature as the track. I have not noticed any performance impact using this mesh value on either my laptop or desktop.
 
There is a much simpler solution. Most of my waygauges on the DLS have spline attachment points for my contact wires. If you lay both track and wires connected to the waygauges, then they stay in alignment, and the correct height for the poles. Just place the poles at the natural kinks in curves (real wire doesn't actually curve). For tighter curves, there are contact wire splines with shorter repeat distances to give shorter straight segments already available.
The only place this falls down is around junctions, where a bit of manual wire-laying is inevitable. Any of my recent routes are done this way if you want an example.

I also have one of my metro tracks with a built-in wire.

Thanks for the suggestions. I still have the problem with the contact wire 20 being 0.1 too high. They don't match the pole height unless I reduce the wire height by 0.1. That is the biggest problem I have when stringing the wire. I will have to try your waygauges.
