Hmmm. I've never had one stretch, that I know of. Then again, it's been years since I did anything like barrels or other performance games. Just to ask, do they stretch just when they're new, or to they continue to stretch throughout their lives? To tell the truth, I've never measured one for stretch. For trail riding (which is all I do anymore, besides training) I don't recommend anything but a mohair string cinch, because a neoprene cinch doesn't dissipate heat well and holds moisture, but I can see where it might be good for what you do.
I think I'll buy a string cinch and do some testing to see how much stretch I can get out of it...just for grins.
