To place a needle valve before the solenoid is fine only if the cavity volume between the needle valve and the solenoid is small, so with only limited amount of pressurized air in this cavity. once the solenoid open, it doesn't "push" too much to the rest of the air hose space or create trouble.
This I knew, but the other points are all valid to take into consideration.
