Love Blackout for sure, it's the best Pro's Pro string that I have tried so far and would have no problem playing with it anytime.
I thought Vendetta was good as well but for me Blackout was the best.
Hexaspin I did not like at all, too muted IMO. As a main in Hybrid it was terrible but as a cross was ok.
Gutex Ultra was a super soft multi extremely comfortable but after tension loss became too trampoline like for me. Did work well as a cross in hybrid setup. But I think I prefer even some syn guts above it.
I know there is no counterpart information, but thought I will add some information about Pro's Pro nonetheless. I would definitely recommend the Blackout to try.
