E-Z17107 is common and diverse in the Eastern part of South Albania and in Central & Eastern parts of North Albania. I don't think Dibrri E-Z17107 can be reduced to mixing with Tosks, because the whole surrounding area (Shllak, Kthelle, Cidhen, etc.) has E-Z17107 results.
Kelmend has one Vlach match from the South, and 3-4 other matching results from the North. Their cluster will be branched out on YFull in the next months.
