The Barracuda is amazing. Extremely under-rated. Duncan’s greatest unresponsive throw ever, in my opinion. I picked one up at Worlds last year because it was the best yoyo available at Worlds last year. At any booth. Its quality is up there with General Yo, One Drop, G2, CLYW, etc…really good throw.
It depends on your funds, honestly. The Raptor is worth owning, it is, but in my opinion there is a difference between a great performing budget metal and a world class throw. If you have the money for a Barracuda I can’t envision it letting you down and is definitely worth the money. If you want to save some money the Raptor does have more color options and is a very good throw. Neither will disappoint you, and you can do the exact same tricks with either, obviously. But there is a reason the Barracuda costs more.
