I'd like to ask if a sefardi Jew from Iberia can use Rambam/Temani tzitziyot instead of the classic Sephardic tying with the ridge.
Edit Reason why I'm asking is because of the rules against changing the family minhag. In this case, family minhag is a genuine mess, with the only other observant jew of the family using both askenazi and sephardic tying.
