I agree with Matt that breaking the boom seems relatively unlikely. In the past, I have also made off to the boom bail myself. One advantage to using a mid-boom attachment is that it facilitates keeping the preventer inside of the jib sheets whereas an end boom arrangement will necessitate dipping the pennant in order to lead the preventer outside the jib sheets. If the pennant leads to a stowage point forward of the main sheet boom bail you would have to dip there as well. Certainly using any preventer is better than nothing. But having it pre-rigged is the key since rigging it on the fly leaves lots of opportunity for error.
I have heard that using a "stretchy" line is favorable so as to absorb shock loads. Triple braid dock line comes to mind. I forgot to mention that one way to make storing the pennant easier and quicker to deploy is to make it out of amsteel. Thread surgical tubing up inside the middle. Now the act of pulling the line tight compresses the tubing which creates an elastic resistance but retains the full strength of the amsteel. Whether you use a hook, eye, snap shackle, or other means of attachment, you will have some elasticity to keep the line tight to the boom. Personally I like having an eye splice which can be slipped over the horn of a cleat, though a hook or snap shackle could be used to make it off to an existing boom bail. You can even make the pennant the full length of the boom and hook the eye on to one of the reefing horns at the goose neck. I dislike hooks and snap shackles since they will inevitably chew the boom and attachment point.
