I’m not a big 5A player so I’m reluctant to give an opinion, but I tried it out with some simple 5A and it worked fine. While I’m at it I might as well say that I have no idea how well it works for 3A since 1. I don’t have two and 2. I still can’t get a good throw with my left hand. Also I wouldn’t use it for 4A since I like bigger yoyo’s for that (simply a preference thing, you can use it for 4A all you like).
