Trying to Create a MTB Skill Tree

I'm working on a MTB skill tree, trying to make it into a skill progression map. I am also working on organizing it into a Beginner – Intermediate – Expert – Pro progression. However, this post is just about discussing the list of tricks and the relationships/progression between them.

This link shows the live view of the skill map (you can click on some of the tricks to pull up how-to videos):

I know some people won't agree with the progression arrows, or even the names of some of the tricks, but that's the point of posting this – I'm looking for feedback, suggestions, etc.

What I've done so far is just based on my own experience and what I've read in articles and watched on youtube. Thanks in advance for your input
