Travis--
But, as Sean indicates, I'd really want to know which courses are available. Though I'm sort of a Travis-nut, I am aware of regions where I'd select the Ross or the available Travis course.
And, since I have not played a MacKenzie course, I'd probably select that, instead of an available Travis, or whomever else's course might be available.
Or, it could be that one of the available courses, by anyone of the named archies, is one that consistently receives good reviews on GCA, or is nationally ranked. I might choose that course, based on factors beyond architect.
