For the record, the Evilbay seller is not me. And yeah, I have some. Just replied to PM. Yes, I saw the deal way back and grabbed some. I was lucky - actual flow is a complex equation involving Cv, orifice size, needle taper, and probably a couple other things, little of which I understand. So the only good info comes from somebody actually testing them in a way that mimics how you'll use them. And that's hard to come by.
