Check out these Gate Closing Springs they sell at Lowes Home Improvement Tim! They cost only $5.67 each and look like they'd do the job well. I suggest using one on both ends if your using it on a really long dipole like a doublet, zepp, or double-extended zepp.

Tim, I don't know how high you want to go but in Ecuador I used a 2 inch and a 1.5 inch,10 foot PVC pipe bolted together to make a mast. The spring in the PVC was enough to keep everything normal in the wind. I anchored the base on a fence post with adj hose clamps. I put a screw in eye bolt in the center of the pipe cap on the top to run the rope through and tied the rope to the fence post. I used one mast at each end of the dipole and the center feed point was at the top of a 11 meter bamboo pole.

:) Hello :)
I use tarred nylon twine 
with my radiating wire underneath !
In a fashion so that the nylon can stretch but my wire won't :)
I have a squirrel problem
squirrels just can't stand antenna support lines !
Least if they cut mine they will get tar on their teeth :)
My antenna is a 135 foot or so dipole fed wit ballanced line !
My tunner can tune out a little stretch anyhow !
I like to use copperweld if I can get it !

Tim-

I'm using a heavy-duty bungee- got it from a big-box home improvement place.  The version I got has carabiners on both ends so it can't unhook.  It's 4 feet long and rated for 50% elongation-  I think it ran about $5.

I've got a fair length of support line threaded through tree branches.  I replaced my original Kevlar support line with 3/32" coated wire cable and appropriate fittings. That way, the branches should give way rather than abrading the the woven line through. That's my hope, anyway.

73- Dave, K1SWL

I would like to raise the far end of the antenna but of course the
higher you go in the pine tree the more it sways when the wind blows.
The wind blows often here in central Illinois!

Looking for low maintenance suggestions for adding a shock absorber of
some sort in the rope that supports the far and. It isn't too practical
to run the rope through a pulley and provide a weight to keep it taught
but that isn't 100% out either. Has anyone had success adding a spring
system, heavy duty bungee cord type absorber, or something else?

Happy New Year everyone!

Hello Tim
You should be able to find better Bungee cords at a hardware/ farm store or a truck stop.
They will still disentagrate in the sun but will make it longer than Harbor freight.

I use old trampoline springs.
They work well.

Howdy Tim,
If it were me, I'd probably try the Pulley and Bucket of Rocks method.

I have used a heavy duty spring attached to the tree with an eye bolt. The spring I used was from the hood of a car. Got it at a salvage yard not sure if cars have hood springs any more. If not a trip to the hardware store to find one but be sure you get a good heavy one as you will find a great deal of tension on the supporting rope. I used parachute cord which I bought at a surplus store it stood up well to the UV and the cold winters I had in Nebraska.
