These comments are exactly why I think we should drop snaps from our 
maneuver schedules.  In my opinion, for a maneuver to be considered a 
good maneuver, it should be difficult to do well and easy to judge.  
Snap rolls don't meet that criteria, when so many people can disagree 
on whether a maneuver on a video was or was not a snap roll.
