If I had the time to restring every match or so, I'd probably have stuck with PE in a full bed. It is great fresh and needs no real break-in.
Since I don't have tons of free time to restring and prefer gut mains setup, MB is a fantastic cross string that I can use til my gut breaks, and I play a decent amount of doubles too, for which it truly excels at the net.
