Here's a picture of an industrial noid (single action) that worked great as a bottle opener, I used it for a couple years with no issues.
And a picture of the NOS pinch valve style (dual action), which gave me more problems than the other style. I no longer run any remote opener.

The amp draw of a solenoid is not an indication of its worthiness for a particular application. Especially if that solenoid has been designed to function in the application it is being used. This particular solenoid I am referring to has a maximum opening pressure of 1500psi and only draws 0.5 amps. It can do that because of the design of the solenoid. If it had a normal plunger designed it wouldn't work.
But like I said before that big of an orifice in the solenoid would most likely require some adjustment to the jetting of the nitrous kit. It is not a solenoid you would just want to go slap on your existing nitrous set up and go run. But it could be used as a primary nitrous solenoid in a system that is not using a progressive controller

The amp draw is an indicater of power and thus the ability to overcome pressure and contaminates. If what you say is true the nitrous companys better stop producing their big 20/30 amp noids and go with the small 7/8/9amp (which they all have) to save money?
The size of the orifice is not the indicator of a/f or jetting but rather an indicator of total flow it can produce. The limiting factor (until you reach noid orifice size) is the jet.
Nice to have some new blood to debate the merits of nitrous. This is how info becomes available to the end users. They must sometimes gleen their own opinion, but for the most part the info is there to make a good judgement.

In regards to solenoids not affecting the A/F ratio this is not always true. The larger the orifice in the solenoid the less pressure drop you will have across it. When the nitrous goes through the orifice it must speed up causing a drop in pressure. This is why going to bigger solenoids on a smaller horsepower kit can often yield more power, you have increased the pressure at the jet resulting in an increase in flow.

Going bigger noid on smaller hp kits, should in fact increase volume not pressure correct?
Just off the top of my head, NOS has a 30 amp biggest dog noid. But what you say is true about most of the noids.

Yes bottle pressure will effect the inlet and the outlet pressures but regardless of incoming pressure the larger orifice will still have less of an a to b change. Now the only thing that might screw it up is bottle pressures above 1050 which is where nitrous turns to a gas and loses a lot of density. At 945psi it is 5.44 lb/gal and at 1040 it is 3.78 lb/gal. That is a change of 1.66 lb/gal before that pressure it can range between .30 and .54 lb/gal per 100 psi increase. That much of a density change may have a larger affect. As up to that point the density vs. pressure was much more linear.
Yes you are increasing the volume through the jet by increasing the pressure to it.
The NOS solenoid you are referring to is the 16010 Super Big Shot. It was a 30amp coil and a .156" orifice. But it was never something that got put into kits and was only really recommended in certain situations. In classes where you were restricted to a certain jet size or to only one nitrous and fuel solenoid.
And I agree with what was said a few posts up about too much thought being put into a dry kit. Just use a normal solenoid and a mechanical opener. You have to put the bottle somewhere and where ever that is probably has room for an opener on the bottle.
