Been playing with rayon wicking on a Ares rta using a Paranormal mod. Taking the RTA on/off to adjust wicking and the flavor was flat...reset the coil resistance measurement and all was normal again. The settings has a lock feature which I have now set on. I guess there is a learning curve when using the DNA250C board, not something I need to worry about with my other mods. I guess simple has it's benefits.
