I agree that they are too strong for the conditions intended, however, it will always be about not only core /cover combo, BUT also how it's drilled/surface as well. I drilled mine weak and smoothed out the cover to have a ball that fits perfectly to the tee; However, I do agree; again as we all know, Roth Grip's lower end pieces are usually FAR from weak, which makes it difficult to choose what you need on the low end.
