That type sling is best when taking classes. Because you are tired of hearing ready - up, your trigger finger couldn't squeeze one more time, your feet are dog tired, your arms are sore from holding that lightweight carbine at low or high ready, your thirsty and hungry, then.... the instructor says .... let em hang. At that very moment a single point sling is gold.

Don't get me wrong. I still like carbine classes. It's just that at my age, a nap somewhere in the middle would be nice.

Keep an eye out for Grover, he is a bad influence. : )
