I keep the RG-6 coax runs in separate conduit from the UTP runs.

Hmm.. Why? Shouldn't be any effect either way.

Reduces problems (you never know who will follow you) with pulling future
RG-6 cables. Also the bend radius tolerances are different. IF UTP
cables are within same pathway the pulling crew has to be more gentle and
careful.

I see.. I never had to work with multiple different types in one pull.

Now if you have ever worked a large cabling installation ... you know that
words "gentle" and "careful" are a foreign language terms to many cabling
pulling crews.

VBG! Yes, pull till it parts, and then back off a little.

There was this time in the Ala-Moana building, when I was installing coax
for video from the first to the 25th floor. We decided to to it from the top
down, so somewhere along the way, threading the cables down the core, the
end cap came off. A couple floors later, when we went down to take it the
next level, we found the raw end sticking inside the cage that surrounds the
440VAC busbars. The other end of the cable was already connected, so that
would have been rather exciting on many levels!

Although when I have traveled with these crews .. they referred to the
airline baggage handlers (pre-9/11) as gorillas (former TV ad of a
logistics company).

I saw a UAL baggage handler slam a suitcase down on the belt so hard once,
that his feet left the ground. I rarely put anything more damagable than
clothes in my bags anymore.
