The right size pin means alot!!!!
the higher the number the littler the pin size is..
so a 25 gauge needle is smaller than a 18 gauge needle...
now to the jacket... cc and ml are the same thing... it is the amount of liquid that you need to take... best thing if you are starting out is to use a 5ml jacket.. it's easier to hold on to than a 3ml jacket pin..
length... no smaller than a one inch needle for the thigh and shoulders... for the gult use and 1 and a half inch needle... most of the time if you order 1.5 inch needles just hold the needle out about a half inch when your hitting the thigh and shoulder..
gauge size... you don't want to go too small or to big for AS.. too small and you'll be drawing the sa out of the amp for an hour... too big and it will hurt more.. i've found that 23 gauge pin works good for me.. everyone will tell you what they like but that me 23 g... draws nicely and i can't push the gear in to fast so less pain...
and you will find it to be to your advantage to get some extra needles... alway want to use new needle to draw with and to hit yourself with.. extra needles save you alittle money because then you aren't tossing out unused jackets...
now to the best place to get them...
