I have a Hybrid Hitman. If I were you, I’d go with a Hybrid. Its a tad less responsive. Black Knight is good for 5A, but the X-ConVict was made by JD, so if you want to go with a JD collection. But both yoyos are great. I don’t like the round rim shape on that. Hitman is smooooooooth.
Well the Hitman and Victs are pretty similar (Unless it’s a Hybrid Hitman). If you want a different feel, then go with the Black Knight. Otherwise, go with the Hitman.
