Dynamic Exercises To Aid Back Lever?

I'm at a loss to figure out dynamic skills which aid the back lever, beyond movements from inverted hang to german hang in various body positions.

What other options are there?

Slow backpulls helped me alot.

To be clear, we're talking about the movement used here to return from a german hang to inverted hang?

Skin the Cats, a good ring support and all that it entails (ring dips and pushups). Headstand/Handstand leg lifts might be another.

Yes, I did them as slow as I could (in my case tucked).
