Can anyone recommend something a little smaller to fit my vision spinner. I've got the vivi nova tank and it take 3ml of juice which is great for all day use. But when i'm at home i like to try something a little sweeter. Maybe just a toot or two. What would be the best option. Currently i'm using a genesis 510 atomizer cartomizer combonation and dripping a little fluid directly onto the atomizer. Works fine too but i want somthing a little better that i can try several fluids one after the other............
