Pic won't post but did my first attempt at dual coils on my trident. Did 5 wraps of 28g wire for 2 coils and came to be .5ohms. With cotton wicks it hits nice!
Hope your svd and 30 B's work better than mine. My svd shuts off randomly all the time and the fire button barely ever works. The 30b was good for 1 tank, now pisses out juice like crazy, took it all apart and still leaks.
