I had some time to look this up and found the following: Page 6 of Samson Rope's technical reference guide for Amsteel indicates that if the rope is bent around a surface the diameter of the surface edge should be AT LEAST 3 times the rope diameter and preferably 4 times the diameter. I would estimate the diameter of the rolled edge on the clark drip rings to be 1.5 to 2 times which is too small.
That said, I believe the small edge diameter of the Clark drip rings would just result in more rapid wear of the rope. Amsteel has amazing strength properties but it is subject to wear via abrasion. Everyone should inspect their whoopies from time to time for signs of wear. The same Samson Tech guide gives some info about typical wear and how to spot it.
