I
I saw your videos.....your clouds aren't that large. I used to blow those size and density clouds with a Nautilus with a 1.8 ohm coil at 11 watts. I do notice that with with super low subohm coils, Claptons, transformers, etc., I don't get a significant increase in the volume of the cloud. Where I really see the difference is the density. The cloud can be so thick that it is difficult to see through it.....which is a bad thing if you're driving and you blow the cloud right in front of you.That's how I am. I only sub-ohm now, so I make little clouds default. I never vape inside of places that I can't, but if I am walking around outside and someone comes near me, I will go out of my way to make sure it doesn't blow at them. I was at a friend's apartment the other night and they don't mind me vaping inside, but they had some other friends come over later. When the other friends arrived, I started going outside because I didn't know them or how they felt about it initially.
