I'm a few weeks away from buying a new single-wide garage door, manually
operated. Stopped into a showroom yesterday when I didn't really have
enough time to talk for long with the guy. He pointed out a type of spring
system I'd never seen: A coil wound around a shaft, with the whole
assembly installed along the wall above the door opening. He said
"Somewhat more even lift compared to the springs you're accustomed to, but
probably not worth the $28 difference unless you're getting an electric
opener...". Then his phone rang, and one of his installers walked in with
a clipboard and a question. It was 10 minutes before closing time, and I
decided to stop back earlier next time.

Any thoughts on this type of spring?

Either spring system should work the same on the door opener or not. If you
are installing the system yourself you may not want the torsion system. One
slip while tightning the springs and you could be hit by the tightning bars
and be hirt very bad. If being installed for you , then no problem.
