That's a good point about if they already naturally throw nose up maybe don't tell them to change their grip, they can experiment with it later as they settle into the rest of their form and it's easier to isolate and test something.
However, if their are, say 5, very common grips the pros use as their primary / default, chances are one of them will fit you better than the others and possible feel quite good overall and result in a shortcut to solid grip if you tried the top ones rather than a random sampling or the first thing that felt good to hold (might not feel or be good to throw).
Now if every pro is way bigger than you then it might not help, but usually their are some normal sized pros, too.
The chances a new player comes up with something novel entirely on their own that is very good are small. So I still think sampling pro form to find a start is best, then modify to novelty from there.
Pro form is a way to see things that work, figure out that key point, and then look at how to best use that position of power from their form.
So, one way you can use pro form to help someone is when someone naturally does some things another pro does, so you can reference that persons form to help get them in line without making massive changes to a persons form.
But for trying to outright emulate any pro, you're trying to emulate something they have spent 15 years working on and developing for their body and their movements.
I had an argument with someone who told me I was stupid because they wanted help because they were emulating everything that simon does and they wanted to get further throw. They threw like 250 feet maybe 280 based on looking at their form video.
The person then proceded to argue with me how wrong I was cause he was doing everything simon did. Which he wasn't, I digress.
The little things people dont know is what us coaches are here for. To see the important details that drive the in your face things.
This is something I deal with when I teach shearing. Everyone is paying attention to what my right hand is doing. Which is 10% of the work. Not the 90% of the work my other hand and my 2 feet are doing to hold the animal and move it around.
Trying to emulate pro form is basically doing that, emulating the 10% because you cannot see the other 90%. And even us as coaches cannot see all of that 90% because we have no data on how to see how they are engaging some muscles, or what they are thinking about at that split second.
So, how do we teach that other 90%?
We cant. Not in either place.
You can be shown the movements, the places, the positions. but you have to personally figure out how to make them work and sing and be in harmony through practice.
So, the reality of teaching in a lot of things is you can really only teach maybe 50-70% of the overall skills needed to be 100%
So, you gotta look at where you're at learning when it comes to emulating others. Do you wanna build your form off of 10% of available data, or 50 to 70%?
Also also, I said naturally nose down, not nose up.
People who think they are experts hurt them by trying to change their grip to be "proper" and cause them to throw nose up. And it will out right ruin their game. That's the whole crux of what i'm saying here. Grip is super important for us to focus on, but were not going to get any real data from pro players, they throw what they found works for them and their body flexibility.
What we need to understand is what changes when we start moving the disc around in our hand for our grip and how it affects the nose angle for the attack of the throw.
I've thrown some insanely wierd unconventional grips when I was looking into this a few years ago, because I really really struggle with nose up throwing. I got plenty of speed. 60-70 range on speed, but my discs go 350 and stall. Why?
Nose up, but were talking 1 or 2 degree's.
And that's all it takes for a great shot to turn to complete shit.
And in some of these wierd grips that make absolutely no sense whatsoever, the disc comes out nose down/on plane. So, there is a lot of room to learn here.
