JPALS is probably what ensures a '3 Wire'. This seems to be part of what a 'good' carrier landing looks like for grading purposes. It would seem to me, now, which wire you take is less down to skill and more to systems. Perhaps there should be a part of the JPALS code to alter parameters in order to vary which wire is taken such that one particular wire is not used more than the others. I get that there are pros and cons to that suggestion.
