Imo best option for Turkey is Hande as Opp! Turkey doesn't need yet another OH, we desperately need an Opp and there are still no options so why not make our 19 y/o star who is a better Opp then OH anyway an Opp. Meryem can only kill perfect sets, Polen is only tipping the ball, both Polen and Meryem are slow, Neslihan is getting older and that's it. We need Hande as Opp! Someone make it happen pls. Vs Brazil Guidetti tried it out and it worked very well don't know why he called Melis Durul now. I don't see how and why Hande still is an OH.
With this roster I would try
Dicle/Beyza as MB duo's, Fatma/Meliha as OH duos, Ezgi as setter, Hande as Opp and Melis Yilmaz (L)
Sub Meliha with Seyma for more defense and Meryem with Hande if she struggles. And send Melis Durul home as Cagla too
