You're welcome to throw your rope away after a single use if you're uncomfortable with it. I was never uncomfortable with mine.
> However dynamic properties decline with use, especially after many falls, and if you want to risk excessive shock loading of your body that may result from a big fall I think you are foolish.
What do you mean risk, I actually took countless falls on it with no perceptible difference in the impact on me over time or between older and newer ropes I had in circulation, I certainly never came near feeling the rope would hurt me in a fall for lack of stretch. If a rope was getting stiff and uncomfortable to fall on I'd have stopped climbing on it.
> I remember some Italian paper that indicated a year's heavy use degraded the dynamic properties to a third of a new rope (in a standard test rig... normal belays would be more dymamic)
As you say, we don't climb in a test rig.
