So hey there, Been awhile since i've been on here.I came from using the kanger topbox mini setup and the rba,then I dropped my mod and the tank broke.So after that I went to the aspire cleito 120 tank and the coils really sucked the $$$ out of me burnt hits all day defected coils, I had one pack of coils with no coils in two of them( no wire), store wouldn't even give me a refund on them,and you could tell they weren't messed with either. So finally i said i'm done with tanks and store bought coils, about a month ago i picked up a wismec indestructible rda real deal and a velocity styled rda, clone for myself. So on black Friday i managed to score a wismec rx200s for $30.00 cad. coming from the kanger 75 watt. I'm currently messing with the wismec rda on the single coil set up,using my own made twisted kanthal 24g, coming in at 0.4ohms, for now i want to stay around 0.4-0.5 ohms. What would my benefits be of going towards the dual coil set up? I dont really hear of alot of people only using single coil setups? i know it will use more juice. more battery. How often do you guys change your cotton and dry burn the coil? I find every morning my cotton is dark brown so i change it out daily.Not a big deal i can do it pretty fast. Im also looking to build my own claptons i was thinking of 32g and 26g kanthal what do you think.? So finally after 4 weeks now of being on an rda all I can say is why didn't i do this sooner lol, i'm still learning lots but taking it slow.
