Honestly, and I'm not saying this to be snarky, but because I've been n NADAC too long I consider hoops and jumps as interchangeable for handling/line purposes. And other than the barrel not being out there, and equipment being different I... see no major differences between that and the novice regular runs I did with Molly at the end of last month, though, yes, the obstacle spacing is closer than we use now and a-frame and dog walk seem more narrow.
Its good to hear it has stabilized, there was a period where it seemed like there where small rule changes every trail.
The obstacles are identical to standard equipment. Nothing has changed there.
There are huge differences in running a course with jumps and with the obstacles either being close or wide open like in your courses. In FCI we can face wide open courses, that mix in technical handling, in our local league we get tight and much closer spacing. As a handler you can easily be with your dog when the jumps are close, you can get front crosses in, but with a big dog it can be hard to make the turns. The handling style is very different.
Not having jumps changes the handlers timing, my dog jumped 20" in NADAC, in USDAA 26" and it there was a huge difference handling those courses, in USDAA I could get crosses in, In NADAC I got spins as I was not able to be as clear with my handling.
At the time if I had been committed to NADAC I would have spent a lot more time working on obstacle commitment and driving ahead of me, instead I had a dog who excelled at snooker as he was very responsive to my position and motion (still is, he is a challenge to drive). I regularly train at a lower height than he jumps at, if we can be fluid at a lower height I will have plenty of time at full height.
I have already mentioned last weekends seminar which was conducted by a Spanish World team member, I ran the course with no bars (my big dog has been having a training break and I have to keep how much we work down) and it was huge a challenge, there were some sections that without the bars made it almost impossible for the human and so we put the bars up in those areas and it made things possible, jumps also tighten up the turns, without the bars his turns are much wider as he is running flat out.
In my opinion the bottom line NADAC is its on style, specialized handling has evolved to run the courses (some of it transferable) many top trainers are not equipped to help students on NADAC courses, it is outside their comfort zone. The handling styles we started talking about have evolved to run "standard" agility, FCI, KC, AKC, USDAA UKI/UKA etc, most of the handlers that developed those techniques have never run a NADAC course.
