I've had this debate with my friend so many times! In personal belief, I came to the conclusion that it would most likely be an icewing. Being that rain is a main component of ice, and ice is dominant over rain. My friend tried to say it would be a snowwing, and she wouldn't explain her reasoning.
Like darkstalker, it would look too different to be with icewings. Ergo, it lives with rainwings and classifies as one, even though it has a few white scales.
