I always use a 1 hinge limb hanger for my bow, but earlier this year I got in a stand with a 2 hinge already up in the tree... so I used it.

mid way through the hunt I heard a sound and looked over to see it spinning on the tree and getting ready to dump my bow. I took a wild stab at grabbing the bow and got very lucky to catch the top cam with a finger. was very close.

lesson, with the 2 hinge ones, you have to be careful with weight distribution
