1/15/2016: The grooved grips have helped a competitive blind golfer. Here is the testimonial.
Lanny,
I hope you remember me. I am the blind golfer, in San Antonio, that you sent some sample grips.
I had the grips installed and they have helped me tremendously.
My club face is very stable through the shot.
Yesterday I ordered a complete set of grips.
