With all the respect, for me, wicks always give me this "funky" whick-y taste and gave me nothing more than troubles.
If i were you i would explore other alternatives.
From simple cartos or cartos in
tanks, to rebuildable atomizers like the Line V2 or the DID for a more advanced user..
I know you are looking for a solution for your ego-c atomizer, but trust me and...explore...
You will thank yourself you did.
