I couldn't agree more on all three points. Learning curve - yes, spaced coils - yes, no dry burning - yes. Once I started following those simple steps, I've had great success with nickel.Congrats and good luck with your nickel build LiveLong.
Be prepared as there is a bit of a learning curve with nickel. I only do spaced coils as I seem to get more stable builds that way. I also do not dry burn nickel.
Oh, I'd throw in one more, tempered nickel - yes. I hope it becomes more readily available sometime soon.
