I've made countless threads on strings. I've written in even more playtest threads than I can think of. Today, I played a set with Prestige Pro strung with Black Magic mains OGSM crosses at 49/51. I played no worse with that than I ever did with Gut/Poly or full poly. Maybe it's taken longer for me to realize it that some others, but today confirmed it for me: a poly/syn gut hybrid is just as good for me as anything else. For the first time in a long time, I'm content with my strings.
