Sorry for not sugar coating things. If you think I was blunt, go to SETPRO. You want brutal. There it is. My advice to you still stands and it wasn't intended to be mean or to say your mechanics suck. You have some challenges there and I outlined a couple. For example:
If you really look at what I said there, you will find what I believe to be some direction for you. Sideways momentum generation with a longer stride. Getting your body to help you throw the body as opposed to simply spinning and then throwing with just your arm. Those are areas you should do some research on. They're complicated and difficult to describe in a post. There's a lot of good material on this site about these things and I'm very serious about you doing that research on your own THEN coming back with questions.
You'll learn a lot more that way than me or anyone here just saying "do this". After you've read about the things I noted, we can have a really good conversation.
In short, I believe I've given you the best advice I could at this point. Get self-educated a bit first and then our discussions will make a lot more sense. I, of anyone, am not averse to helping someone out. Quite the opposite. I've spent many hours doing just that. Tanner can attest to that, I'm sure, as can many others.
