You have to use a dama that the string/bead pops out of very easily. My metallic ooz works really well. Basically once you've grabbed ball and the Ken is about at the nine o'clock position (on it's way up in the arc) you have to give the ball a quick sort of tug towards the ken to make the bead pop out. You have to make sure that when you tug it the string/ spike hole is oriented more or less right in line with the string.
Once you have the bead out it's kind of a moment of commitment, where you have to let go of the ball and make a grab for the bead. Try to make the transition smoothly and quickly, you'll probably drop your dama a bunch though.
To get out of it the handroll is all I've really come up with. I suppose you could grab Ken and try to spike it, I haven't tried that yet though (...just got an idea of what to film today, hehe).
I'm interested to see how you got te bead out though. Honestly sounds tougher haha
