I'll add on questions regarding pins.
I have a couple proffasi packs I want to use. I've been told to draw with a larger guage and shoot with a slin guage pin 25 g or smaller). I've only got a choice between 23 guage pins or a fixed pin insulin needles, 27 to 29 guage.
Can I draw with the insulin needle? Can I shoot with the 23 guage? (I'm planning on shooting under the skin in my belly).
