I have heard the 'dimpling' called 'crepe' because the texture is like crepe paper, and some folks like it. I had 'Age of Miracles' and it did this quite a lot, but the petals did not have good substance and it did not hold its color well, so I don't have it anymore. I do like the crepe texture though.
Here is 'Gold Crepe', another example of a crepe textured daylily:

I love that color, Dennis, so if it were mine I would keep it at least another year or two to see how it performed. Like Tim said though, if it is not holding up the blooms, I don't think another year will make a difference and would not hesitate to cull it.
