The point of the two valves is that you ALWAYS have TWO nozzles, you can use without turning the nozzle selector.
Oh, I see now. But why a ball and a pull? I guess it would be interesting to see how a stream's performance varies when coming out of two different valves.
Anyway, I guess I will discuss my concept now.
As you can probably guess, it's based off the Triple Aggressor design, but with much needed upgrades. For one, it's CPS based instead of PR, it has multiple nozzles (I think 3 is enough, because in real life, I almost never use the nozzle settings in between the smallest and largest. Riot blasts are fun, and they come in handy in close quarters.), with a unique way to turn them.
You could further expand on the nozzle switcher by placing it closer to the pistol grip area for easier access.
Well, where I put it, you'd use your pumping hand to pull it (There would be one on the other side for left-handed users.). And yes, the idea is to have it rotate the nozzles just by pulling it once. That's another area where only having 3 nozzles helps (The maximum amount of times you'd have to pull it would be only two.).
The sidearm, which is also CPS-based, would be sort of a last-resort blaster. You could keep it pressurized through the whole battle, and use it whenever you're in an emergency situation. I don't know if I mentioned this or not, but it is compatible with a QFD (I thought about making the regular blaster QFD-compatible as well, but I decided not to.).
Instead of having a "Soakerball" err, soaker on the bottom, I decided to put a water balloon filler. Water balloons are of course, much better than soakerballs, and you can carry a whole bunch of them, and just fill them as needed. Unlike the Triple Aggressor (I think.), the switch cuts off water flow to both the bladder and the mini-pistol, so you can fill the water balloon simply by pumping. I think it would be easier to control then the Triple Aggressor's mechanism (Unless the TA does use the same method. I don't know.).
The reservoir (I used the circle tool to make it, that's why it looks so... round.), has a Max-Infusion enabled cap, which will hook up to a larger Aquapak than those tiny 100oz things. I'm thinking about the same size as the CPS 3000's backpack.
I mean the Pulse master is for sure a great gun, everbody here would like to have...Me too
Yeah, I'd rather get this then the Vanquisher.
