The 430 is springy indeed. Not too much worse than the 317, but noticeable.
I threw a 7 wrap single coil in, went to pulse it, and the wire immediately drooped and contacted the base of my atomizer where it tried to weld itself and also snapped back at the post.
After cleaning that mess out, I threw a practice coil that was 12 wraps in that I had only made for getting a feel for the resistance/springiness in because I was impatient and wanted to try again right away. That one was too high resistance to tc on, but is great in watt mode.
Then I tried putting the tank top on instead of the dripper top for the atomizer, made contact and shorted/burned out the coil. :/
Hopefully I can cut the user error out and enjoy some tc out of it, but it'll have to wait for next week, too much homework right now to keep playing.
