Aussie halyard question

My Aussie style halyard comes with a small stainless halyard "keeper" (fairlead?) for which there are no layout numbers or instalation instructions. Does this small keeper just perswade the halyard from getting hung up on the battens? I was all set to install it about 3 feet below the yet to be installed tang...it looks like that in the illustration. At the last second, I felt bad putting 2 more holes/rivets in a space that may be airtight already. Do I really need to install that little halyard keeper?? If so, it seems like placing it on the side would direct the halyard out of the way of the battens as apposed to installing it on the front of the mast like the illustration showed.
Also, is my jib halyard cheek block, on the bottom of the mast, rendered unnessessary by the Aussie style jib halyard??
Thanks all you commenters for the input...I want to do this right the first time! bones.

The halyard can come down the side for best batten hang up prevention, but down the center is best for equal mast bend issues (both tacks).
