For clarification, my original post was only in reference to the opening sequence. I agree that most of that course was super fast and flowing and easy to handle. For me its the combination of the two extremes "fast and flowing EXCEPT RIGHT HERE and RIGHT THERE that I personally object to. It feels like a trick...that will trip up dogs if the handler is not PERFECT.. and quite frankly who is perfect all the time? Not me. I selected this opening sequence because of the naturally fast line (from the dog's perspective) from 1, 2, to 3 to a super flat turn to #4 with #6 looming as a WC. Three were many HARD landings after #3 and some ugly scrambles as dogs reorganized themselves after #4 due to the flat turn from #3, either by being on the wrong lead.. or perhaps just because the dog fell THE ZONE.
Someone said she'd slow her dog down from the get go to get a nice efficient line from #1 to #4 and yes. That worked well at the trial I was at.......slower dogs and small dogs looked perfectly fine running this sequence including my mini dog Lil. I don't think people were intentionally trying to slow their dogs down for handling purposes though.

Also for clarification, I look at international course maps with the same attention to FLOW as I do when looking at NADAC course maps. IMO any style of course can be designed with FLOW in mind including international courses. Back sides are often easier to get in flow than front sides if the dog has been trained to have an independent performance of various jumping techniques found on international courses.
A friend of mine recently posted this run that shows how an international course can be run in flow. IMO a well designed course offers handlers the option to create a flowing path for their dogs...if the dog has the training on board to do his job independently. As you will see if you watch the video below, Dawn is a great dog trainer (her dog knows his job well) so she can focus on her job, which is showing her dog the fastest, most flowing line through the course. Dawn is a master at finding the best line for her dogs.. big and small (which is rarely the tightest line) and then handling the dog's path incredibly well. As a result her dogs all run with confidence, boldness, nice extension, and most importantly in my book, her dogs run and jump with natural motion. Its not surprising to me that Dawn ends up on the podium time and time again.

Everyone seems pretty set in their opinions... including me.. so perhaps this entire thread is pointless and we should all forget I ever brought up this subject. I'm thinking this is a brilliant idea.
Can we all agree on this point?
