Which ST to choose?

[Vitesse]

I have been wondering which striker I should choose. I play 4-1-2-1-2 Narrow Diamond, but I don't really know which striker is more of a use to me.



As you can see, my ST "Koen Reintsema" has higher attack stats, and also one-on-one scorer. But Ivan Slavchev is 18 years old, and also almost 6*

Thanks for your help!
