Hi Steve,
There was a similar discussion only a few weeks ago. You can find all of
those messages here:

.
The consensus seemed to be the suction method, that is using a shop vac to
draw the future pull rope through. This would work after the pre-existing
cables were inside, so long as the conduit was lightly loaded.
