Do you switch needles after you draw to pin?

[zaggahamma]

You don't NEED TO, but it can make things easier. The reason most people swap needles with AAS is because they use different sizes to draw and inject. It's kind of generally accepted that even pushing a needle through the rubber stopper can dull it, although I'm not sure whether this is actually true or not. Hospitals inject with the same needle they draw with from everything I've seen.

i've tried both and definately feel a difference
