CWD Needle Attacker, ~17g.

• With the center metal component of the CWD accounted for, Needle Attacker weighs in at roughly 2g.

• It is a free-spinning and small plastic CWD frame with small protrusions that realistically do very little. Because they are free spinning and small, they not only don't frequently make contact with opposing combos, but they also don't do very much at all even then. 

• Had this CWD been static, perhaps there would be some use for it outside of adding a bit of weight to your Attack combos. As it stands, you can throw this on a lot like Free Cross, when you have nothing better and want to tack on a couple extra grams to a combo. 

Best Possible Combo:

AR: Circle Upper

WD: CWD Needle Attacker (with Metal CWD found in RBA2)

RC: Grip Flat Core (Ultimate Version)

Game Plan: Try to pretend you're using the slightly heavier and static CWD Defense Ring. At the most minute level, the difference between the two CWDs exist. In practice, it really makes little difference and Circle Upper will have no trouble doing what it does best - throwing opponents out of the stadium.

Tornado Change Core, ~3g.

• Features a mode change gimmick reminiscent of Plastics' Dranzer V2 BB. Tornado Change Core has two modes: Sharp Mode and Hole Flat Mode.

• Unlike an RC like Dranzer MS' RC,  TCC is automatically changed mid-battle. At high RPM the Sharp tip ejects from the center hole and later retracts when enough RPM is lost.

• The creates a unique experience where your Beyblade starts off fairly docile and speeds up later on. Normally this is exactly the opposite of what you'd want, though.

• Surprisingly, TCC is actually quite fun. Its height makes it so ARs like Samurai Upper will always make contact with opposing ARs and not their CWDs, unlike shorter more traditional Attack RCs.

• While not quite as reliable as a Grip Flat Core style RC, TCC is actually a choice you shouldn't count out immediately. A very interesting choice for Attack types to say the least.

• In the ideal scenario, initial contact creates a huge hit that either knocks out the opponent completely, or would be enough to almost immediately shift to Hole Flat Mode.

• In Hole Flat Mode your combo can shadow the newly knocked around opponent and possibly finish them off. As weird as that sounds, it isn't terribly uncommon.

Best Possible Combo

AR: Samurai Upper (Right Spin)

WD: CWD Defense Ring (with Metal CWD found in RBA2)

RC: Tornado Change Core

Game Plan: Launch flatly or bank into the center of the arena, as this where Stamina and Defense types tend to head to. If you can safely land an initial big hit, Samurai Upper has the ability to knock out opposing combos outright at this height. If a knockout doesn't occur after the first hit, it may have been enough of an impact to already change TCC into Hole Flat Mode, where Samurai speeds up and stalks the opponent in a flower pattern-esque way to ideally commit the finishing blow.
