The red fins are different from mine. Mine look more like Lufubu to me than any other comp that I've seen.
There is no official classification for "fire fin" comps, nobody knows for sure what is and isn't a fire fin. There are only opinions, mine were imported as fire fins but who knows. It's definitely a tag line that brings more money, that is the only thing we know for sure. From all my research, basically any comp that has red in the fins is labeled by the collectors as fire fins which will bring them more money, no collection point is assigned to them which makes me even more suspect. I'm happy with mine and to me he's quite special... and so far everyone that's seen him in person has been blown away which makes him even more special to me.
Until there is a formal classification for "fire fin" comp's, we'll never be certain as to what actually is a "fire fin", it's all in the eye of the beholder. That's my opinion anyway
I also don't think we'll ever see a formal classification, but we'll continue to see them imported as such... again, my opinion
