OK not really sure how to search for this one I have tried a few searches on here and Google with no helpful results. I just picked up an aga-t2 last night built my first wick and coil, it came out to be 1.5 ohms which is perfect since I'm running it on an ego batt. However reading through the forums I have seen coils referred to in a x/x format. I don't understand what this means. How do I know what my coil is how do I determine the 4/5 coil for instance?
