I suffer from Canadian bias, home course bias from high schoo (my dad joined The Summit GC when I was 17), and lack of play at most of the great courses in the world, and even STs "best" courses, but having read quite a about the guy and some of his tracks, I would assume that he would be well respected on the elite list of ODGs?
Ian Andrew, Jeff Mingay, Mr Doak and others will hopefully weigh in on this question.
What he did at Banff, Jasper, Highland Links, St. George's, Capilano, Summit, Cataraqui, Westmount, etc, etc, is a pretty impressive body of work. At many of his sights there were pretty intense routing, elevation, tree and drainage challenges and it appears that he was able to overcome them and produce courses that have absolutely stood the test of time (at least those that have been well maintained).
He was my first round pick in the GCA Draft - so that has to say a lot!
