Ni80 20awg on a cloud competition 0.16 quad coil in a Patriot RDA. Wicking was organic cotton, all I mainly use for my wicking due to ease of getting ahold of, flavor, and ease to build with. Not the only device that had an off metallic taste to it, the Innokin iClear30 and iClear16 tanks that came with my SVD's and MVP's had the same distinct taste come out at the back end tone of any flavored liquid I was using at the time, not the nickel I was tasting I learned after using Ni200 in one of my subtanks, believe it was the chromium.
There in too is another reason nickel builds don't bother me as chromium is a bit more toxic than nickel to an extent I have heard. With my palette its all a matter of getting used to tones to not pay attention to them, had to do it with almost everything I've vaped with, silica, ekowool, SS mesh and SS cable in genesis tanks, kanthal, nickel, cotton, organic cotton, rayon, bamboo, hemp wicking, etc, just can't get over the taste of Nichrome it seems, could even be due to reaction with to the few silver fillings in teeth I still have. Took me almost 6months getting used to metal drip tips is how sensitive the metallic tones are to me which is surprising given I smoked for the better part of 25years to learn just how sensitive my taste was to even such minor tones within a month of fully transitioning to vaping from smoking to dual using to vaping. Doesn't help I also have OCD, and since started vaping, I like to control just how much I am taking into my body from types of foods to types of flavors I vape on, etc, I've become mildly eccentric in my health habits you could say.
Not trying to scare anybody off from using Nichrome, just giving my experiences thus far
