I will give this a try!
The reason I used Modes for the $j was that the text output to PDF was not displaying correctly without changing the way it was displayed, but I wanted the other two modes to display correctly on the computer. It has been awhile since I did this, so I would need to take another look as to why I left out the \boldsymbol command. Perhaps it changed the display in PDF format, but I will need to double check.
I do remember that the \jmath did NOT display correctly in TeX (PDF) mode. It was giving me an empty box for that character. So I just went with the hat over a regular bold j.
Thanks again, Davide!
