Probably a little late to the party but I am going to say this anyways.
I just saw Shion Araya’s tension hook-ninja vanish thingy and I realized that it uses the mount you get in after beefhook, it is pretty fun actually to do them back to back. Here is the best tut I could find on the tension thing:
It took me less time to learn how to juggle (Juggling was 2-4 days, Beefhook was 2-4 weeks). so frustrating, you can still follow the normal tut for the rejection thingy.
I wanted to learn Ninja Hook so badly that I decided (as tempting as it was) to not learn anything else on your channel but that, I guess I can cheat once.
Something that REALLY helped me was learning negative 1.5 hook (they are the same thing, just the hook is from a standing position instead of a mount) which is something nifty to know in general.
Updating this topic because 1: I found out that you can Beefhook from a Reverse Hook. and 2: You can do that Rejection Ninja Vanish thingyinto a Ninja Hook, which is awesome and immensely satisfying, @EOS44 I expect an instagram post using this element soon. (just kidding but it would be cool if you did)
