While the Standard Kit will certainly be enough for most situations, 
some teams will pick up a few extra items to extend the capability of the 
ARIZONA VORTEX
For instance, if the rescue team wishes to build a high equal-sided tripod 3.0m
in height for confined space entry with plenty of head room, ordering 2 extra 
lower legs (making the total nine (9) instead of seven (7) will allow each leg 
of the tripod to have three (3) total lower legs.
