Why do you think you need such large gauge needles for? 25 works great for anything, hell even slin pins are easy to get the juice out.
well I'm really gonna try this. I have to see it with my own eyes. slin pin for test? what 27 28 30 gauge? just don't see it happening. 25 gauge is fine still gotta press plunger pretty hard.
About. the 22 gauge 1 1/2", that's all they had at the time, the fluid gets in quick and it hurts no more than the 25g
