Here is a much better fallaway imo but the video isn't as slow but if you look close,you can see the movement on the arrow and this appears to be a pefectly tuned setup.Notice how late it falls,perfect for hunting imo.

Here is another of a fallaway,notice how the arrow starts to fall with the rest,use the berger hole as your reference and then watch how it comes back up at the end(still using the berger hole as a reference.)


Ever wonder why nock travel is important,here you go.

This shows what the arrow should be doing as it flies downrange,notice how the arrow moves.

These videos show part of the reason why I am not a fan of the wb,it just restricts the naturall flow of things too much imo.

I wish I could find a spring steel video/



BUT,to be honest,the biggest reason that most pros use a spring steel is it is SIMPLE and there is much less to go wrong.Plus they are a breeze to tune.AND by tune,I mean fine tuneing to the umpth degree.
