You don't need to believe the hype to buy. If you shoot your bow better without a stabilizer, then shoot it that way. If it rocks back after the shot, who cares? Rocking back on a level surface with your arm extended horizontal is not unusual, many bows do it. What makes a bow rock forward is putting a 12oz. weight on the front-bottom 1/2 of it.
So when you see guys and their bow rocks forward, realize that they have a stabilizer on it.
Enjoy shooting your bow. That's the bottom line.
