Jumping Base
Note: The Takara version of Jumping Base has very fragile plastic and one should avoid using it.
Weight: Hasbro: 9.8g plus Flat Tip (0.23g), Ball Tip (0.22g) or Sharp Tip (0.18g)
Main gimmick is a large spring that lets it bounce around
Second gimmick is three interchangeable tips – sharp, ball and flat, which come with both versions, though they are molded differently.
Right Spin Only
Very gimmicky, but a pretty fun part
Very unstable, poor Defense.
Ball tip is arguably the best option due to coping better with the off-kilter stability throughout the battle, especially as the Sharp tip only increases this issue and the Flat tip has poorer stamina while doing little more of use.
Closest thing to a useful combination with it is one designed to jump away at the end of the match (or cause a violent upper attack-based collision while scraping), however even this is at best a luck-based strategy, and even for a luck based strategy it is still not that great.
The Hasbro version's tips fit on Neo SG (Double Bearing Version) Shaft's tip part part. The former is interesting for looking at how different tip shapes perform on bearing-supported shafts, however, and has some interesting results with the Ball tip being quite competitive with Customize Grip Base (being a slightly more predictable if a little less stable version of the original ) and the Flat tip being okay if outclassed for Spin Stealing Attack.
Mold Difference:
The Takara and Hasbro releases are quite different.
The Takara version uses a shaft in the centre of tips to insert into the spring and retain the tip, while the different spring used by Hasbro which curls into the centre of the tip connection area necessitates taller sided tips without a centred shaft.
Takara's version has a taller but higher tension, thicker gauge spring compared to Hasbro.
Overall though, neither are terribly useful, and the Takara version is fragile (though it may be possible to transplant the spring) so the Hasbro version's tips make it preferable.
