We've used that stuff in PVC conduit and it tears it up pretty bad.
Definitely do not use that stuff to add more wires in a pipe later. It
will rip the jacket on cables pretty fast. Ask me how I know. :(
Probably fine for the initial pull in an empty pipe. Mule tape all the
way though.

We use regular poly pull line all the time:

It’s cheap and more than strong enough to pull the 1/2” rope up
and back down the tower. We use it a couple of ways:
a) Climber takes the bucket of string, a pulley, and a couple of
small weights up the tower. Tie the weight on and throw the
string down. Cut the poly and repeat. Tie the two ends of the
poly together through the pulley, attach the rope at the bottom
and pull it up. If you rig the poly onto the rope correctly it
fits though the pulley without having to mess around up top.
This method works best on towers with a number of obstructions
the prevent the next method from working. It doesn’t work well
when it’s really windy.
b) Climber takes the pulley with the line already through it up
with him. Helper on the ground keeps the tag and and the line
coming out of the bucket under control. This is the lightest for
the climber but doesn’t work when there are a lot of things for
the poly to snag on or where the climber weaves in and out of the
tower.
The cathead winch will easily pull the poly line.
We don’t try to salvage the poly line - it’s cheap enough that we
just recycle it when we are done (ok - who am I kidding, we wad it
up and throw it in the trash can).
