smallest gauge for winny

[Keep it beefy]

I'm currently using 28 or 29 gauge insulin pins, and drawing fine. Do you think I'm missing some of the powder drawing with a needle this small, or am i fine? It's white in the syringe, so I know it has some winny in it, but tell me what you guys think.

I would go with 22g.
You might be losing out on some amount with a small gage like that.
