I own a Summit Viper XLS,and have had no problems with it.As far as the bar getting in the way of your shots.I have not found this to be the case.Bring the seat adjustment straps up close to the seating platform,that way when you stand to take the shot,the bar will be sufficently low enough,enabling you to take any shot,that may present itself.Good Hunting!
