Review on FVW Climbing Carabiners Locking Hammocks by Ray Cole

I climb with them. I actually have two fliplines, one orange and one green. When crossing branches on a tree, I put on both lines and climb the tree with one. Then when I get to the branch, I put the unused line over the branch and attach it to my harness. Then I unhooked the previous line and climbed the branch further up the tree. I used to use green carabiners on both lines. Then I wondered if I might have disconnected the wrong line? Seeing these orange models of the same carabiner, I quickly decided to attach the orange carabiner to the orange line and leave the green carabiner on the green line. Problem solved! Simple problem, simple solution. Simple guy.
