I first stumbled upon this new strat randomly 2 days ago when I was doing attempts, but I could never figure out how it get it as it was seemingly random for me. But then RunStrafe had also discovered this strat and managed to pull it off in his runs. So with some help from him I decided to give it a go to see if it worked on Default (as he did it on Legacy).

Well it turns out it indeed works, as I expected, and it saves a decent amount of time. It's not as impactful as on Legacy due to slower turns and whatnot, but still a good improvement. This was my first finished run with the strat that had a clean entry to the zipline, so I'm sure it can be improved a bit more. However the first Wall Boost is a bit limited since if you have too much speed going into the second one, you don't really have the time nor positioning to get this new trick. But a faster second Wall Boost and smoother turn into the zipline should still shave of some time I'm sure!
