Matt,
I like your additional list, but lots of those courses you list have numerous weaknesses. I think Weston is probably the prime candidate and they are getting ready to do some work, so I have hope. I will give you my two cents on each.
Summit - Great land, weak architecture.
Mississaugua - Too many changes through the years to be great. It could be near 25..
Thornhill - Barely remember it, but I always remember wanting to play Uplands next door more.
Highland - Not seen it.
Burlington - A bit of a mess, trees overhang the fairway, 17 is unbelievably out of character with the rest of the course. Pretty bland on the upper holes.
Weston - See above.
Kawartha - Not seen.
Grandview - Mingay is a big fan, I am not.
Osprey Hoot - No disagreement, good, but I do not think it is better than any on the list.
Beacon Hall - Probably one of the courses that should have made the list. The style is not popular, the green complexes are a little overshapped and six and seven are dogs, because of the environmental permitting. The drastic differences between the front and the back hurt the overall course. Still, if this had been 25, I would not have complained.
London Hunt - See Osprey Hoot, though I think this lacks character.
Taboo - Redundant, bland and nothing that makes me want to go back.
Rocky Crest - Have not seen, but I bet I would strongly consider it in my 25.
Wildfire - Really nice course, good bunkering, despite the white sand, some really good holes. The land is a bit plain and I cannot see which course it is better than.
Firerock - Similar to Wildfire, but better land, worse surroundings and the irrigation pond on two and seven hurt it. Loved the bunkering and I expect to see more of it from Tom. I loved a few of these holes and am looking forward to my next round there.
Pulpit - Largese, everything the Paintbrush is not and I would play one round of ten there, only so I knew I was right!
Philippe,
Some photos to prove my point:
Looking back on the first, which shows the trees that encroach on the first. Of course this hole will be gone if they go ahead with the reno.
The fourth, arguably the most spectacular hole, but those trees left....
The sixth, great hole, but look at the left side.
One more to show that I am not against Montebello, I do love playing golf there. I can understand why it was one of North America's most prestigious club for the first half of the 20th century.
