The only complaints that we have is the quick wear down of the exterior.  As seen in the photo on the right, the fine leather's porous quality, while increasing the softness and play-ability of the ball, quickly degrades the appearance of the ball.  The SV-5W Gold looked beat-up and worn after just two weeks of play.  While true volleyball players know that its not how the ball looks but how the ball plays, for club owners, a bunch of shabby looking balls may not sit well with parents paying those club dues.
