I think we're talking personal preference here. I personally would just look for a quick changer and be done with it. But that's me.
HOWEVER....do note.....Sheridan's can be funny about HPA. I've had some that work OK....but most fluctuate velocity. Either you can't get it up to velocity or it's over velocity, or it's spiking and dropping all over the place. They love CO2. Just thought you should note that before you invest money.
