Hi, I am new to disc golf and had some questions about which disc(s) to get and how to throw. I am 13 years old and skinny, I was wondering what kind of discs I should purchase...I have no discs, but I have a budget of $50 dollars. I also have no idea how to throw the disc the right way...so a few pointers would be awesome :) Thank you so much!
