Its really hard to look ahead and no how much flying a category will have. Things can change quite rapidly depending on manning, what season and aircraft mod lines in operation. The 767-4 guys on reserve will get the winter off as a large portion of the fleet goes into Mod for lie flats. They will however get worked to death next summer. The MD manning in the FO seat will change fast with hiring. That change could go either way. Flying a lot when new is not a bad thing however. It gets you off probation quicker.
