Sad to report a negative result: I strung Pro Hurricane in the Mains and Cyber Flash in the crosses @55 and one of the mains broke in 1 set. And I never break strings. I know generalizations are often wrong, but the more I buy Babolat products, the less I think of them (except VS gut). I asked my stringer if it could have been damage during stringing, he said "no."
I didn't really like the way that setup played either. The power/angle was too low to what I am used to.
Going back to my crack of strings - Lux ALU mains - for now.
