Really good vid. I too like the dialog boxes.
Some comments:
Might be good to add a dialog box with the pattern info. Maybe if possible get a few more details on the pattern, like length, maybe volume. Just to give everyone from the causal viewer to more experienced bowler the most information
Liked the comparison to other balls, maybe if possible, add a second shot where you overlay the current reviewed ball with the older balls or show the actual lines of where the balls were thrown together on one shot, so you can get a good side by side comparison. Or if that isn't possible ( as I know not everyone has the software capable of this) maybe add a second shot with the older balls throwing the same line as the current one, so we can see the difference at the backend, show it leaving a washout, or pciking 3 off the right, etc.
Lastly, in the attempt to please everyone. Maybe, if possible add a few shots on something other than THS. THS tends to make all the balls look similar. On a sports pattern, we could really see the difference between them and highlight the current ball.
One of the better vids I have seen though.
