Hi Ben, thanks for sharing your video!
You Cairo Crack looks good to me. I had a little trouble getting a decent crack out of the circus crack variation too.
Once you figure out how to form the loop with a little wrist action it all falls into place.
Overpowering and speed are my bad habits too.
I did perform the crack initially without it, but after a few days I felt justified in using some artistic license for this particular challenge!
Good work

Hey Matt I look forward to seeing your cow whip!
