Mongoriller, there is no “BEST” yo-yo. It comes down to what you preferences are, and what’s best to YOU.
The following are MY choices, and why I like them. My opinion may not be the same as yours.
1A: YoYoJam X-ConVict - I just love the shape of this yo-yo. It’s wide and smooth and can be set up to someone’s preference easily. Plus, It has great grinds (Especially when satined)!
2A: YoYoJam Sunset Trajectory NXG’s - I like the shape of them. They loop well due to their excellent response system (I like them better siliconed). Their weight distribution is awesome, and they aren’t too heavy.
3A: YoYoJam Kickside and YoYoJam Speedmaker - A pair on any of these are wonderful for 3A. They’re both plastic, so they’re durable and won’t “CLANG” when they hit. They are both a moderate size, so they can maneuver easily. They’re both Hybrid response, so if you have two, there are many different response combinations you can have. They both have different weight and shapes, so just pick which one you like better.
4A: YoYoJam Dark Magic - This is my favorite 4A yo-yo, because I do 4A “grind” tricks. The metal rims on this yo-yo make grinding easy. Plus, it’s big enough to make 4A possible, but small enough to challenge your skill. My favorite after the DM would be the BigYo.
5A: This is my main style, so I have a lot of favorites. I like heavier, and full sized yo-yo’s that are durable. However, sometimes there are exceptions. Here are some of my 5a favorites: YoYoJam Kickside, YoYoJam Black Knight, Duncan Freehand Zero, Duncan Freehand 2.
