And the entire point of this thread, being educational, is lost as the beginner is not going to read through 6 pages of bickering and try to make sense of the info, some of it wrong. The most important factors to me are as follows. Learn how to build a coil and check it's resistance, know the lower limit of resistance for the batteries you have in your mod. I played it safe and just got the 30 amp mnke batteries. I know I could build a coil as low as .4ohm and be safe. All the bull.... about whether one is safer than another will be lost on a newbie, same with the discussion about what constitutes a mini or micro coil etc. If we could make such a guide then that would be helpful. 6+ pages of overly technical info will never be read by the average Joe. I appreciate the sentiment though.
