I love my Summit Viper X4 and think it's pretty quiet. Like VAhuntr, if I take my time and don't rush anything to get setup, I am fine. The rubber coated cables on the Viper don't bang and clang around, unless I hit them against the stand.... I found that unpacking a climber can be a tad noisy, if you are not careful. But hooking up the cables around the tree on a Summit Viper are not loud.
