David, I tend to disagree that we can leave this discussion up in the air.
My knowledge of Bugis society, culture & history is presently very limited, & my way of thinking about the keris is that we should gain that foundation understanding before we try to understand the keris itself.
Going back twenty or so years we did have active members of this Forum who had some knowledge of Bugis keris forms:-

in this thread we do have some people who seem to be quite positive of geographic locations associated with various forms of Bugis keris dress.
They might be correct, they might not be, but I do believe that their comments are worthy of taking note of.
