A game I am currently playing a lot is called Roller Mania. Last fall I attended the United States Disc Golf Championship Tournament. The Winthrop University Gold course is a great course. During the four rounds of play in the tournament I saw all these players kicking my butt with rollers. They had a shot that I did not possess.
Rollers are such a tough shot to learn.
A roller is just an extreme anhyzer. Turn your turnover a bit more and it rolls. Seemingly anywhere it feels like without regard to your wishes. But somehow all these top pros have this shot down. It is an awesome weapon.
