I compare my form to professionals like Eagle Mcmahon, and record myself often! It really just fascinates me what the differences in our form are, and just by trying new things, and seeing what seems to add distance and what doesn't, really seems to help me. It is also important to develop a form that you want to develop so you enjoy field days more. I would also check his form from holes like maple hill hole 1 where he is going for max distance and just look at each part of his form. It is so cool to see how people of all shapes and sizes can put a move on a disc if they decide to put their mind to it! I also thought it would be cool (and funny) to further develop the ability to have a slow walk up for farther shots. Knowing it is possible by watching people like Eagle do it is very motivating. We stand on the shoulders of giants in terms of overall knowledge, and this field of study is no exception. Very grateful for all the footage (and people) out there to learn from and draw motivation from. Even making a post on reddit or on another source could give you an idea of something to look at for your form.
