I tried the the Viper when I was at Six Flags Magic Mountain last summer out side of Los Angeles, California. The Viper was probably the most shaky roller coaster I ever tried out and not in a good way so thats drags down what I think about it. However, this have speed. height, several loops and corkscrews so it does more than okay and I would rank it 3 out of 5 points and I would recommend it.
As always I attached a video from TheCoasterViews on Youtube if you want to check out the ride here below.
