Thank You SSG. I do not like to have arguments on the forums, but only to help each other. Some ppl try to start fighting with me and I simply don't reply back. I can value, and take consideration of someone's opinion but when it turns into an argument, then it is not worth the time. You may simply see things a different way, and that is OK.
To answer your question: The 21 wraps of 28g ESG titanium was a dual coil on Esterigon. The resistance was cut in half due to this so it ended up being 0.4 ohms. If it was one continuous coil, I'm guessing it would be in the range of around 2.1 ohms.
Now that I think of it, maybe I won't try the 50mm titanium after all, due to the fact that even though the ohms might be low. A thick coil takes longer to heat up. I will just stick to 28 or 30g for now. Here is a pic of 21 wraps/dual coil 28g titanium in Tilemahos.
