Silly me I thought you were talking about the BR rank Wing EW Ver. Katoki :X
I don't usually have any problems with WZC because I usually use scissors; even then WZC doesn't have the best defense so it's not too terribly difficult to deal with if you're using other types.
And indeed Wing suits are hard to differentiate; at least the Frozen Teardrop suits have a different name.
