I did more research after writing yesterday's blog post. I still wasn't really that at peace with my decision. I wanted to ensure I was doing the right thing for myself, and my family.
After a quick review, I found out (I'm not sure how I missed this yesterday) that Rav Yosef Karo (Maran Yosef) actually writes in the Shulchan Aruch about shavoah she'chal bo as the Jews of Rhodes, and Sefardim (not to be confused here with Mizrachim), practiced it.
That led me to the key question here: does Minhag Yerushulayim (Jerusalem custom; That of the Sfradim who lived here, as the Ashkenazi Jews that lived here had their own Minhag Yerushalayim) take precedence here (as it was in practice before Karo wrote the Shulchan Aruch) as I am a resident of the city. As I am not a permanent resident of the city (at least not yet, so this may be revisited in the future) and have a halachic backing for my minhag (custom), I do not feel the need, or obligation, to change it.
