Didn't have much time to write a more thoughtful answer before. BTW thanks everyone for the suggestions. This is a remarkably helpful and generous forum.
Originally, I got into vaping nic from the other side -- my ehpro mod was purchased to power a Saionara atomizer. Doing research on coil options for that atty/mod settings/battery selection/etc., a lot of the resources were from the e-cig world and I ended up picking up a lot of info by osmosis. So I got that there are different vaping styles and that I didn't know mine. I also got that there are a gazillion flavours and that I didn't know what I was going to like.
I decided to pick up the Wasp because (1) it was inexpensive, (2) reviews indicated that it was easy enough to build on that one could try different coils and (3) as a dripper it would be easy to try different liquid ratios, flavours and nic strengths.
For ~20CAD at DashVapes on Adelaide I could dip a toe and see if vaping nic was something I wanted to take up. Plus it's getting cold in Toronto and smoking on the balcony is losing some of its charm. Having the option of scratching my nic itch on my sofa in my PJ's has a certain appeal
That's it. So I started with a simple ~1 ohm coil (god that thing was ugly, I wish I had taken a pic), then tried larger and smaller ID, more and less wraps, higher and lower wattage, more and less airflow, higher and lower PG... you get the picture. I went with whatever felt good and so here I am today at 2.63ohms/10W.
I feel like I've gotten as close as I can with this atomizer, recognizing as
@cigatron pointed out that although it is amazingly versatile, the Wasp isn't really designed to be used the way I seem to want to use it.
So I'm going to move on to something that works better for me, which I now know means a fairly-to-very restricted airflow. And a tank for when I'm driving. I love my little Wasp tho, and won't be retiring it anytime soon. It's just too much fun. I mean seriously, what's not to like about this?
