Selectable Dual Bottle Setup
... meaning the feed line would be open once it is unscrewed from the unhooked bottle, thus making an open path for the N2O to go when the hidden bottle is opened via remote bottle opener. Does someone offer a checkvalve I can put in line to avoid the need to plug the open end? Any other ideas on this? Niiiiice!
watch out for this guy

My tips are things I've seen along the way, can't take credit for alot of them.
Its hard to hide a whole system, so I've found its easier to hide "part" of the system. Let everyone know you have a kit, but make easy to "disable" or disconnect, even if you're faking it. Just be careful, some grudge guys get really pissed if they suspect you sprayed them anyway. If you're gonna hide it, spray small. Its pretty obvious when you hit a car with 150-200 shot.
And I agree about the completely hidden system... that's difficult. Letting everyone know you have spray and then making it appear to be non-functional is usually easier, and lets the other guy "know" you're not spraying.
