I've been reading about practicing driving with a putter to get your form down. So, I researched what people were using for this and went out and bought a nova, soft magnet, pro aviar, kc pro rock (I know, I have a sickness and it wa payday). Anyways, I started throwing them just under 100' but eventually worked up to about 150 after a couple hours. The problem is, almost every time I throw the disc is wobbling. I know this is killing my distance, I just can't figure out how to stop it. Any suggestions would be appreciated !!
