I fell on the way down while climbing down from a fixed position stand once about 4 years ago. Since then I've been using the ascender and rope assembly on all of my fixed position stands.
To each his own but I cringe every time I hear someone say they don't use a harness. I'm pretty resiliant, but I found out the day that I fell that I don't bounce well when I hit the ground.
Thud.
ooooooooh.
