Replying to Inverting off an up rail?

Ok so I am really contemplating this at the stowe jam this weekend if they set up their up rail well enough.

I am curious if people who have inverted off an up rail before could post here and let me know how they did it.

Basically I figure you just gotta sack up and pop and pray. Other then that hoping people can post their advice.

Videos will be posted of attempts for sure, cus either way I am going for it, providing the set up is legit.

Figure it will either make for some good merk footy or some solid landed tricks.
