The best way to learn to use a hook is to practice with a small harmless snake. Hooks can be tricky with fast snakes. I practiced with my adult male pueblan. He is like a rocket when you touch him. The best thing that I have found with larger snakes is to hold the hook upright to hold back the business end (Head) and lift the body with your other hand.
Dont lift a large snake with just a hook. Some people use the two hook method and others use the large python hook from Midwest Tongs.
