Garth/Tee,
In what situation will you ask your partner for help then? Do you two umpire on an island and leave the other ump (either BU or PU) to fend for himself and make a two-man system literally two men using a system?
There is nearly a need for a little help at some time or the other. When would you ask for help, if ever?
The reason they use more than one umpire in certain levels is for the "help" that each gives.
