I'm sorry if I am having a blonde moment. I'm not sure I understand your question. Since there are no controls on the R9, what ergonomics are there?
To me, even though they are slick as in smooth, your skin can stick to them somewhat, more so than OEM grips.
However, I think you can not beat the feel And function of VZ.
As stated on another thread, to enchance the function of my designer grips, I "grooved" the thumb area on both panels. I think it improved the looks as well. It looks better than the picture. They do not look so "plastic".
