No. More Gadbuursi live in K5 than Awdal and Djibouti combined. Borama is only a town, not a region. K5 is not a monolith but is very geographically spread out. To lump them together is not wise. Maybe we'll do differences based on actual towns rather than pooling together people from different sub-regions of K5 while keeping stock of family backgrounds. It's also not smart to think all of SL is the same or that they are 1:1 matches for people in parts of K5. Gadabuursi/Samaroon, who live in Ethiopia, are often surrounded by their sub-sub-sub-sub clans. You'll need regionally specific and finely-grained data before you make any leaps or generalizations.
I don't think their Omotic admixture gives them a particular look. Kinky hair (though less likely) also exists in the Copts, and they are mostly Eurasian. Care to tell us why the Oromo, who have the most Omotic admixture, tend to have wavier hair than the Habeshis, who have less (on average)? Also, Barwanis and Cadcads are highly South Asian-shifted.
