There seems to be something screwy with Mr. Kluznick's logic.

Under the paragraph Line Size he states he wants four feet of stretch but
will have to add more snubbers to get the desired SWL.  However, adding
snubbers will decrease the stretch as the load will then be spread over
more snubbers.

If one has 4 feet of stretch with on line then adding another of the same
size will produce two feet of stretch (at the same load) since each line
now has half the original load.

A SWL of 15% of the ultimate breaking strength seems unrealistically low to
me (I smell the company lawyers at work here).  I would choose the line to
give the stretch I want and ignore the stated 15% SWL in favor of, say, 50%
of ultimate.  

For those "very conservative" folks one could rig a second snubber with a
higher breaking strength and rig it slack to come into load when the first
one stretches to the limit one desires.
