Well, there are different materials for ropes and most of them are
suitable for tower haul ropes. (However, I would draw the line on old manila
ropes.)
Climbing ropes are pretty sophisticated due to more exotic materials and
much more testing and documentation. If you can afford them, they make great
haul ropes. The kernmantle (braid-on-braid) construction is pretty abrasive
resistant and offers years of reliable use. Lots of yachting rope has the
same construction but is more generic. My personal haul rope is some of the
nylon yachting rope and has over 700 days of use on it with little wear. One
day's use may consist of dozens of lifts so it's obviously had thousands of
cycles on it.
In choosing a rope you take into consideration cost, elongation
(stretch), material, suppleness, etc. They all have pluses and minuses but as
long as
its rated for what you're doing, you should be good to go.
