Nah... Ferreas videos were really shitty. The ones I posted are low res clips and the ones we used in our booth looked really good.
BTW we make Ferrea's springs.
And as for the springs spinning. Spinning helps with valvespring seat/retainer wear. Some spin faster then others and some barely spin at all. I've seen springs spin one way and then stop and spin the other way. Really cool stuff.
Matt, That spring was not broken or fractured.
