Interesting to see so many votes for Babolat. I just got their "9-pack" team bag, and I have several issues with it that make it much worse than my older Yonex bag.
First, no way is it a 9; it's a super-6 at most. Second, the zippers don't feel heavy duty enough. They have teeth that snag and misalign all the time.
There are some things I like about it, but overall I'm disappointed.
