Heya Lord Vaako! Welcome to the NuT house
I actually answered this very question a few days ago so I will link it, but I am happy to field additional questions, etc.

The justification MKR presented above is true, also - pre-steeping and managing inventory for another dozen SKUs is a challenge, especially for a product that (to be honest) didn't sell that well. Before we took down 24mg first we assessed how much we sold... and we also looked at the people that bought and their subsequent purchasing patterns. The people who were drawn initially to 24mg fell into two categories... either they didn't order again or the moved down to 18mg relatively quickly. We haven't really polled the people who didn't order again, but it was an "aberration" for us because our retention rate is extremely high. If you compare the total number of orders to the number of customers we have actually touched, the average number of orders across my entire book of business is over FIVE. Statistically, if you try us, you're likely to place a subsequent order... but that didn't seem to happen with 24mg vapers. Strange, right?
I'm shooting from the hip, but my feeling is this... "If you want to ruin a perfectly good bottle of liquid, put 24mg of nicotine in it." Now, I totally understand some people prefer more (one of my best buds on Nu-Vapor, one of our regular contributers, is a DIY'er named Hawk who has never actually placed an order on the website, and vapes nothing but 33mg because that's what he has determined works for him). I totally get it - some people need more and I don't knock that at all... but I wager the transition to 18mg will be easier than you think... especially if we can talk turkey about deliver devices. Shoot - I'll even toss loan you a dripper with a pre-build coil that will make you a believer...
If I had my choice, I would make 0, 3, and 6. No 12, no 18.
Sorry I just got around to revisiting this thread. My go to device is PapsX and right now as we speak I'm vaping out of a Magma with a 22g G-plat Elite parallel coil and cotton. And yes I've read the warnings about G-plat but had to try it. When I can't drip I've got a few KFL's running dual 28g micro coils and cotton.
I vape a lot as it is. I also vape in my office and while I'm gaming, so I the fewer hits I have to take, the better. All my juices are 50/50 blends and 24mg. I doubt I'll ever go down to a lower nicotine level. One good pull from the magma and I'm all set for a while, and my flavor is great. Could it better at 18mg? I bet it would, but like your friend, I'm happy with where it is.
I just accepted your friend request (thank you for reaching out) so please let me know if you ever end up adding a 24mg line where the flavor is just right. If that doesn't happen, no hard feelings. I understand this is a business. At least you're not telling people that you're not selling 24mg because it's not safe.
