Viper and Scream Machine may have similar heights and the same inversions in the same order, but they are NOT identical. Viper is a much more compact design, and IMHO a much better design. I think it's the best coaster at SFMM, whereas unless I'm taking someone with me that hasn't ridden it before, I won't touch Scream Machine. Scream Machine and Shockwave were nearly identical layouts, but Viper's the "ugly cousin" (who actually delivers a quality ride experience)
