Nylon 3 strand will elongate about 50% before breakage.  That property 
is great for anchoring or towing but awful for guying or lifting.  The 
energy that can be stored in a piece of nylon rope is impressive and 
some very nasty accidents have happened since nylon rope also makes a 
very good saw when it relaxes from breaking.

Because sailboat racers want no stretch lines for halyards and sheets, 
several low/no (some even less then 7x19 wire rope) stretch rope 
materials are now available, at reasonable to astronomic prices.  New 
England Ropes StaSet polyester braid in 7/16" diameter is my favorite 
for gin poles, lifting, rigging, block and tackle work, etc.  A moderate 
price, easy handling and knots, very durable, fairly low stretch (4% at 
30% of breaking strength).  see

Most marine chandlers carry it, e.g. West Marine.  Also, on ebay.
