I'm fairly new to dripping so when I decided to start building my own coils I did not know what wire gauge to use so I just guessed and ordered 24,26,28,30 gauge each has 100ft on the spool. After awhile I found my sweet spot using a 5 wrap 26 gauge duel coil coming out to .4 oHm. I have found various builds both single and duel coils using the other gauges but for the life of me I cant think of anything to build with the 30 gauge wire! I was hoping everyone can give me some ideas on builds using the 30 guage. I really like duel coils but I'm open to all suggestions but I don't like to go below .3 and so far I Only know how to make single and duel coils. I have 3 RDAs (Mutation X V4, Fishbone RDA, The Madd Hatter) So I only have experience with 3-4 post designs any suggestion will defiantly be appreciated
