Liquid/ re filling cartos- advice

[jagerlager]

hello everyone!
I am currently using Green Smoke products, and am looking into using the leftover cartomizers to re-fill with some different juices to keep things interesting and find out what I like before jumping into a better system.
So far I think the Green smoke flavors are pretty good I am a fan of the "mocha" and menthol, the tobaccos are so/so, and I would like a good cig like tobacco.
I was thinking of ordering a few 15 mil bottles from johnson creek. "original tobacco" "espresso" and the menthol one as well.
any advice on other juice suppliers, or Johnson creek etc...?
I like a good throat hit and lots of vapor.
Thanks.

I liked this place when I was just starting out, their sample packs are pretty cheap and their juices are very good imo - Velvet Vapors - Home

VelvetCloudVapor.com Has great tobacco mixes, and love their "catherine the grape" and "sour skittles".

How many ML would you say could fill a green smoke cartomizer?
