i wouldnt they cost pennies bro
All you have to do is draw up enough air to push that oil through and you have no waste.You guys must use cheap ass needles....... The ones I use do fine doing multiple vials then go in smooth. They also have such a small waste it is like nothing. Want to know how cheap your needle is? After your next pin pull back and let the oil resettle. You will be amazed at how much you do not get...... The good ones will cost you, or will they.....
As long as ur not using the same needle u draw with to pin.I dont see a problen with drawing with the same needle from multiple vials.
