Fear on vault can be a very bad thing, because you need all of your power and effort to do a proper vault, especially a tsuk. I broke my hand on a tsuk, so I can see where you are coming from, but the key is to get a good spot from your coach and just go for it. If you balk, you will possibly get hurt, so the key is in knowing that you MUST fully commit to the vault. The first vault will be scary, but you need to trust your training and your coach to take over for you. In other words, get out of your own way and let your body do what it has been trained to do. Get a good run going and don't think too much. That is what the training is for. Your body and muscle memory will take over and once you perform that first vault, you will have broken that mental barrier and your confidence will improve dramatically. Good luck
