I think my favorite moment in freestyle so far was in January when I landed my first beck atw. That trick is literally the reason I started freestyling, I saw macca do it randomly on youtube and I was instantly hooked, from then on I made that my number one goal. To finally achieve it was an amazing feeling, I literally landed it, caught the ball, laid down right where I was for like 15 minutes, and then ran to tell all my freestyle friends; I still get a rush every time I do it.
On the other hand I've had many times where I got so frustrated I literally punted my ball as far as I could. Goes both ways but thats why I love freestyle; work hard through all the challenges, and you'll see progress.
