Thanks for the opinion mate. You are right about the Pontid element, majority of us are pontids , some north pontids, but pontid is not similar to lets say greek or portuguese med. The ratio of light eyed/ dark haired people is very high in Bulgaria.
I cant comment about Slovenia Croatia or Hungary because I havent been to these countries, the only Slavic county I have visited is Serbia.
I also have been to Greece, the people south of Solun are really different from Balkan Slavs, some of them are suspicious, Probably they are gracile meds.
Northern Greeks (exception those pontiac greeks who were reselted there) cluster with Balkan slavs because they are simply helenized slavs.
