07/08 will be my third season officiating
VB, my second officiating BB. I really like them both and can't really say which I would choose over the other if I had to drop one.
Obviously, there is no comparison with regard to the physical aspect of the games; BB you run,
VB you don't.
Mentally, my personal experience is that
VB has been more challenging than BB, more so as the referee than as the umpire. I've struggled with recognizing proper alignment/overlaps at serve and making sure that I know who is who in the back row during play.
I have a great deal of respect for those officials who can somehow memorize the entire line up and recognize an alignment error with just a glance. Some of the teams will line up is such a bizarre alignment that you would swear that they are overlapped, yet they are not; others will purposely assemble illegally and then just before serve they adjust to make their alignment legal .. sheesh!
Illegal back row attacks .... I've missed more of them than I care to mention.
And now in CA the Libero can serve .. for crying out loud!
