Nah, I string myself and Zymax strings are damn cheap @rkep
I think i may have to give these gosen's a try based on everyone's opinions. I use Ashaway Zymax 65s at 25 x 27.5lbs on my rackets.
I still have a reel of the version 1 zymax 62 with maybe ~10 string jobs left. I didn't like it for the durability. Yes it played well and i liked it but not enough to string my own rackets frequently. It normally wouldn't survive past one session (3 hours) and the max i had was after 3 sessions in one week.
Got to say it strings well. And yes, it's a hard string and feels very similar to BG80. Bear in mind Gosen strings are not made in the same factory as Yonex but I'm sure they understand the technology within the string.
I'll be coaching over the next few days and will report again soon.
