Common issue that is solved by unlearning common instruction. Rather than hooking from bottom forward, hook from top back if that makes sense. You were taught to hook from the bottom with the shackle so the shank would travel further to come off. I have no idea what the new idea is to hooking from the top other than the way forces work or space was spec'ed. Class 5 and more are the same way.
