MrPlink - I don't know on what load you meant that but with a 1.3ohm the drop is ~0.3 ohm and it's probably due to the age of the
mod, I got it about 2 months ago and never cleaned it with alcohol, I guess I can get it to about 0.25ohm after cleaning.
crxess - I'm not sure how is it possible to take the insulator out, I tried it few times but it sits flush inside this metal "housing" do I don't have any grip on it... from how it feels it may be
threaded and not just pushed there...
Thanks!
