Valley is solid-color. I have a green, which is regrettable, but it does seem to stick out at night, because it's a lighter color.
The elastomer seems pretty nice for the newer runs. Has good grip and durability, like it should have... I've found the Valley to be a very consistent disc. It's not as fast as I thought initially, but it's still very consistent. I have a much better idea about where/when the Valley is going to turn over versus a Trak, which was sort of a guessing game, though both discs are very straight. The Valley is very solid for forehand and controlled driver shots.
