With Test, does anyone just use a 22 or 23G pin to draw with as opposed to something larger like a 20G? I'm worried that the 20G may do too much damage to the vials rubber stopper.

I use 18g, and have never had enough of a problem with the stoppers to worry about it. Even when I've just about used up the vial, none of mine have ever leaked.
True.........the only time I started to notice pcs. of my rubber stopper at the bottom of the bottle was when I was using the original 4mg/20ml of Liquidex.
