from CY Badminton in Seattle. They are very tacky compared to most other brands that I have tried. Also, the foam ridge is quite prominent. You can see the depth in my picture, from left to right: CY, Gamma, Wilson, Head.
The cost was $19 Cdn for 8 grips shipped. The Wilson Cushionaire might cost me $13 each. I have only started using them, so I won't comment on longevity. However, they do seem to be a little thinner compared to the name brands.
