Most 3a pairs trends to be more angular throws. Round butterfly shapes tend to br more centered and to most people heavily rum weighed yoyos are more popular. I personally think echos would make smashing 3a pairs. I also use superstars which I love for 3a
I’ve also heard Ironies are amazing for 3a. I don’t really think echoed are popular seeing as only one professional uses them for competition. As for superstars, when kentaro kimura was on YYF he used superstars for 3a and look at what he has accomplished.
Superstars aren’t uncommon, Patrick Borgerding used them before the MVP came out, and as previously mentioned Kentaro used them to much success.
Ironies are in fact fantastic, lots of players using these.
I use a pair of Crucial Delicious. A really “out there” pair would be the Dif-E-Yo Juggernaut. I only got to play a pair for a bit, but very good. Code1,Code2, Burnside also haven’t been mentioned yet.
Yoyojoker and yoyomonster also put out some good 3A throws. This is all I can think of for now!
Chiefs
SkyWalkers
Code 2 GZRs
Avant Garde 1 and 2
Poo
POPstar
Just about any yoyo that their owners can’t bear to scratch up or are oddly sized such as micro yoyos or offstring yoyos.
