Couple of half hitches and lots of tape to streamline the end of the
cable bundle.
I use 3/16" Nylon and contrary to others have never burned a grove into
PVC yet. OTOH I use copious amounts of wire pulling soap. IF the
cable bundle is going to be long and large, I use the 3/16" as a pilot
line to pull in a plastic covered 3/16" wire rope which is a bit over a
1/4" OD. Again, I use lots of wire pulling soap.
Using this method you can virtually pull a conduit *full* of cables.
You need some one on the feeding end to dress the cables to keep they
from wrapping up. They need to be parallel in the bundle. Don't make
the mistake of taping them together. That makes it more difficult to
get them around bends and impossible to replace one cable at a time.
Again, I can't emphasize the use of cable pulling soap enough.
I've used 3/16" Nylon in the past, but I'm going to change to the 5/16"
poly.
BTW, we pulled the cable TV/Internet cable through about 130-140 feet of
half inch PVC and three Triple ought (000) cables through 3" PVC from
the pole to the meter (bout 120-130')
As a note, any *dry* plastic, or small diameter cable (wire rope) will
burn into PVC conduit bends without much strain. Grease the snot out of
it! It may be messy, but well worth the effort, particularly if the
conduit is crowded and you ever want to replace one of the runs.

I had 5 runs of LMR-400 up the 100' tower and just taped the cables to
tower legs every 3' or so. I'm now doing the same with LMR-600. I have
grounding bulkheads at the top and bottom of the tower.
