Although bounce testing RPs is a good idea, bounce testing hooks is a bad idea. Just think weight, unweight, weight, unweight, shift shift shift, POP. I like to put my hand over the hook as I get onto it, this way it is much less likely to hit me in the face and I can also feel any movement in the placement. By holding your hand over the hook it is far less likely to hit you in the face, I find I receive many more face shots from ripping a nut out with the draw still on, once it comes out it makes a beeline straight for my helmet.
