I just had both of my garage doors replaced - one of the installers was telling me how his uncle, who has done installs all his life, just about ripped his thumb off when he took his eye off of one of those tension springs for a second and it slipped while he was pre-loading it. Not something to mess with.

I've always heard warnings about the side springs, especially if they snap while the door is down and stretching them. Mostly about damage to the car parked under them, though.

That is why you put the safety line inside the side spring style.
