Homer,
If I was to show you two South-Somali girls more beautiful than the couple you saw, would then change your mind and agree Southern Somali girls are more beautiful than Sland girls?
You see how silly your reasoning is? You yourself have answered your own question by admitting you couldn't tell their place of origin untill you recognised QALDAAN accent. Why then backtrack and make the association of Clan and Looks that didn't exist before hand afterwards (after you found out their clan)?
Matter of fact is, it's impossible to tell a somalis clan by looks alone. Therefore, one can't objectively make qualified statement about a particular clan/sub clan and the beauty of their women.
