so i picked up the subtank mini a couple weeks ago and ive been toseed between the rba, or the .5 horizontal rba, then kanger tech came out with a .5 vertical coil. So i picked up one and found it to be nice. Which is where i'm torn. Which one do you all like the best? Also i noticed all are at .6 ohms. Now i expected my builds to be .6 since i am new to building but a .5 coil fresh out of the package running at.6 is a little strange. I understand that mass produced coils can never be bang on, i expect this from aspire since i never had a nautilis mini that was never bang on but i dont know much about kanger tech. I did notice that on the base that theirs a little crack in the 510 connection to the battery. Is this normal or ... So would that affect my range at all? I did take out the new coil and placed it on my mod just to see as is which came up to a .6. So my coil is the suspect. But that crack in the 510 conection is getting me wondering. Any insight and possible fixes would be greatly appreciated. I don't mind the .1 difference so i'm just curious if this is a constant issue or a unique wtf. oh ya i running/using this on a i stick 30w if that plays a role in all of this.
