Thought this might be of use to someone as I couldn't find out much about these when I first heard of them. This Safari sling I've had a year now really suits me. I move about a lot on my perm, no feeders or actual hides possible, and I'm generally there 90 minutes to 3 hours every visit. This makes the gun painless to carry and easy to get into a shooting position without too much movement to disturb whatever I'm planning to shoot. Expensive for what it is and may not suit everyone, but I wouldn't be without it.
