Pneumatic plumbing configuration confusion

[marccenter]

Dear CD,
FRC3548 will be using pneumatics this year and the plumbing configuration that we are using agrees with what is found in the game manual so it should be a legal configuration. However, team 358, which has a great pneumatics web site which is extremely useful, shows a configuration that doesn't use brass fittings and as such weighs less. Furthermore, Andymark, shows another configuration for it's pneumatic system. Which one can we "officially use"?

I am raising this question because in an attempt to configure our system I now realize that other teams may be looking at any one of the three sources and arriving at the competition thinking they are good to go but may not be.

Since it is my first year using pnematics I don't have feel for how "closely" the inspectors follow the game manual configuration. Please weigh in on any thoughts and experience with pneumatics configurations at previous inspections? Thanks in advance
