Oh man my first bunch of supplies I ordered, I got a pack of 18ga from NN and thought 'Oh those 14s will be too big and unnecessary'. Oh my god that was so frustrating trying to suck up VG haha. Finally figured out I could just take the needle off and do it that way hah.
That's the best way I have found too - pour the vg into a wide necked jar and draw it up with the syringe without the needle. I don't like using the cylinder to measure VG - it just takes for ever to completely empty and I do like to be precise. With a syringe I know I am. So far the largest syringes I have are 5ml but I'm thinking of getting something bigger since I am know pretty sure what juices I like and am mixing in much larger batches.
