From Jake Bullock:  
[Slap Jr](https://yoyoexpert.com/products/slap-junior-yo-yo-by-jake-bullock) is an undersized, bi metal iteration of the Slappa, an ultra lightweight slimline yo-yo that I produce in collaboration with genius yo-yo designer Jameson Larkins.

In 2022 we released the original mono metal Slappa in an effort to see if we could create a pocketable, super light weight slimline yo-yo that still had a lot of power and spin time. We realized that goal by utilizing a large diameter, which in combination with a narrow width creates more centrifugal force. It was a hit, a pocketable slimline that didn’t pull your pants down and played like a real yo-yo instead of a novelty. We followed it up with the Slappa SS, a 1:1 bimetal version that drew inspiration from my childhood favorite the H-Spin Good & Evil.

A year ago almost to this day, my oldest friend and yo-yo life partner Randy Shreeves visited and tried out the Slappa SS. He loved it and offhandedly commented how it would be cool if it had a smaller diameter, the same size as his (our) longtime favorite, the Anti-Yo Bapezilla.  
That was all it took and within a few months we had prototypes of an undersized Slappa SS, dubbed [Slap Jr.](https://yoyoexpert.com/products/slap-junior-yo-yo-by-jake-bullock)

[Slap Jr](https://yoyoexpert.com/products/slap-junior-yo-yo-by-jake-bullock) retains the same light weight and slim diameter of its predecessors but shrinks the diameter from ~58 mm to 52 mm. In order to keep the weight up while shrinking the size, Jameson fattened the SS rims and at the same time inadvertently created a rather unique scenario in yo-yo design: [Slap Jr’s](https://yoyoexpert.com/products/slap-junior-yo-yo-by-jake-bullock) rims weigh more than the yo-yo’s entire aluminum body and guts combined. It’s literally majority rim weight, and it shows when you throw it.

I am still forming my opinion on this Slap Jr. I love the 52ish mm range so that’s one check. The width is narrow enough that I am having to adjust my accuracy… and this is a perfect weapon in that regard. The feels of it have taken some time to grow on me. In this size range I’ve been drawn more to the feel of the D bearing and I think that’s what I feel like I’m looking for but missing from the feels. Now I will add that the Slap Jr still feels great with the C bearing. It is very stable and holds tilt and axis incredibly well. I have also been quite surprised on a few returns by how much spin it was still holding on to. I got mine in a trade and had no real expectations going in, but I like it. It’s definitely not a rock on a string as can be the case with smaller diameter throws. It handles way better than I can make it handle, but it’s forcing/helping me be more accurate and that’ll help in the long run. It’s a great little throw and I’m happy to have one.

Ooops. Forgot the pic. How insensitive of me.
