You can use them all. I have a gutted echo carto I use for a cone and another one that used to be a and ego tank atty. It has a wider hole that fits the thicker plastic and syringe modded ce2s. 3ml syringes work best if you ever crack the sleeve. And you can punch a hole in the rubber plunger tips to make a sturdy grommet seal with the perfect diameter. (DON'T THROW OUT ANYTHING EVER. You will be surprised what you find a use for.)
I'm into tanks now, but they are only as good as the carto inside. I think I have enough parts to frankenstein an 808 ce2 tank but just haven't seen the light yet. It'll dawn on me. And there will be pictures.
