Not Larry, but until he gets back on, maybe I can kinda help.
Remember that at the top right you have a search feature, and in this case I know Larry answered that question for us about two years ago. I have found a lot of great things in the history using the search.
Still, sometimes there is sooooo much information it is hard to limit the hits with the right question. LOL
Now, my experience is that the center of balance should be just behind the center of the bait, to just before the center of the bait, depending the shape and overall intent of the glide bait. On my glide bait that I made, I found that I wanted it just before to get the widest glide. I thought that I had it all figured out so on the next bait, just thinner, I weighted it the same and it was all wrong. Oh well, I still have a lot to learn.
Hope this helps a little.
