actually, you can help with fakies.
This is how i learned them and it really works.
When you get into fakie, do tiny fakie nose manuals. like don't balance in a nose manual, but just sort of bounce up and down and keep your front wheel on the ground. And when you feel off balance, kick your back out a tiny bit to the left or right.
Then once you get comfortable with that, start to do the bouncing thing less and less.
