Any tips or advice on remembering the route and the different movements? I used to run SS a little bit at the beginning of the year, but I have since forgotten it and want to try again.

Bro i had no trouble just watched it minimum a couple times, you skip the the parts that dont matter, and you just practise each part of it, (You need a bunch of repels) and just do it over and over until you memorize it, once you start doing runs you should remember it for awhile, aslong as you run it every once in a while
