So true Jeff, I saw a safebloc sling that SamaraiJoe uses that's on Instagram and I'm just mesmerized how he made it/or had it made, but it incorporates an X Ring and a SafeBloc for negative Rigging and his response was that the X Ring allows a tighter bite on the trunk. I'm gonna have to investigate the snot out of this thing! It's a Sling of Beauty! Maybe Jared or Joe would take a pic of this Bad Boy so I can reproduce it. I can't wrap my head around how he can tighten a Sling with 2 fixed ends and capable of wrapping it around the trunk! If anyone knows what or how it is configured, what I'm trying to explain, I would be very much indebted to them! Oh, while we're on the subject of X Rings, crazy me just bought $350 of different sizes and manufacturers of them! I think I'm gonna be really busy for the next few week nights! Now I need some 14-20mm Sirius Bull Rope, I've got miles of Stable Braid and Tenex!
