wow.  Full year?  My coils rarely stay in the RDA over a week.  Not because they are bad or anything, but I just rip them out and rebuild them.  One thing I liked about my cigars and pipes was the build up.  Loading the perfect bowl.  toasting it with a match and getting the false light.  letting it sit a min and then truly lighting it and tending it so that I get the perfect burn all the way down.  Or trimming the tip of a cigar, lighting a ceder splint and slowly toasting the foot before finally lighting it and enjoying the smoke.  With my vaping as was already stated, wire is pretty cheap.  I tend to only rewick a set of coils once before Im pulling them out and rebuilding something different.
