Deep black looks great, and much better than what mav had originally posted. The other two designs - cube and carbon - look horrible. I like MC Escher style cubes as much as the next guy, but wow is that uggo.
How easy/difficult was it to put on (there are a fair number of individual pieces)? Is the adhesive really strong?I have the SGP deep black on and it definitely improved the grip. It was very slick prior to putting on the skin. I believe the one you have pictured is the aki-asahi skin, which is currently unavailable.
