Last week, BUL played with Vasileva as Opp and Rabadzhieva-Karakasheva OHs. Karakasheva is good receiver but not strong in attack...
I think injuries will help BUL, Karakasheva&Rabadzhieva combo is more balanced OHs so that they can use their monster MB Filipova more Moreover Vasileva is certainly more effective as Opp than OH But still will be hard to beat Serbia A
