Best practices for using Constant Force Springs

In Detroit, we noticed many teams using or adding constant force springs to their lifts. We were looking to retrofit our lift with some springs and wondered if anyone could share best practices for using constant force springs? What’s the best way to connect them? How do you mount them? Can you use different springs together? What if they’re not long enough, can you extend? And any other experience you care to share is welcome. Pictures or cad files are especially helpful.

Thanks

Good recent thread on the subject here: https://www.chiefdelphi.com/forums/showthread.php?t=165430

This guide from Vulcan Springs is pretty comprehensive.
