Metal Driger (Hasbro)
Hasbro release of Metal Driger using Right Engine Gear (Metal Semi-Flat) instead of Heavy Metal Gear and Heavy Metal Core, much to the chagrin of fans.
Weight: 4.7g
Right Spin:
Flat faces with vertical lines for Spike Attack
Recoily, once controlled it has decent power but not enough to be truly competitive.
Triangular protrusions get in the way a little, worsening consistency.
Left Spin:
Well angled and well shaped contact points, and triangles don't get in the way too much here.
Does have somewhat limited reach however.
Very similar in shape to Cross Attacker (albeit mirrored), but contact points face just slightly further outward which makes all the difference to its effectiveness.
Competitive Smash Attack AR in this direction.
Best used with Ten Wide for better contact point exposure.
Weight: 16.1g
Heaviest legal Weight Disk.
Compact size and weight distribution makes it excellent defensively but not useful for Attack
Excellent for sustaining RPM – helps with defense, grinding, force smash, upper, and also defending against the last three.
Primary choice for Compacts, Traditional Upper Attack, Weight Defense, Circle Survivor Defense, and a competitive choice for Force Smash and Driger V2 combos.
With faster Attack Blade Bases (i.e. Defense Grip Base (Tip Inverted) and SG Grip Change Base Tip setups), Ten Heavy can be used without loss of speed, and its high weight becomes quite useful with Attack Rings such as Square Edge and Hayate Attack Ring, improving their rotational Smash characteristics however the reduction to the flywheel effect otherwise provided by Wide Defense or Ten Wide tends to result in more recoil KOs. It is nonetheless an acceptable option.
Overall a very versatile Weight Disk and a must-have part, outclassing both Heavy and Eight Heavy in all aspects, as well as being generally superior to Heavy Attack.
Weight: 11.0g
More of a small flat tip rather than Semi-Flat, as the edges aren't bevelled.
Moderately aggressive movement, but not all that much.
Final Clutch Bases are generally better than First Clutch (which tend to break flower pattern or even Self-KO), only due to the chance of a desperate last minute attack which generally lacks the speed to do anything but sometimes even manages a loose flower pattern. Were the available bases less tall, this might have been useful with an Attack Ring like Square Edge, however Engine Gear setups are too tall to make use of it.
Overall though, a lighter and less bulky Normal Base (Wolborg 4 Version) or Normal Base (Rock Bison Version) is generally a better way to go unless you want to show off the EG Gimmick. In this case it is best to not wind the EG.
Right Engine Gear (Metal Flat) tends to do everything Metal Semi-Flat aims to do better, making it heavily outclassed.
Generally better than Left Engine Gear (Metal Semi-Flat) due to access to good overhanging ARs such as Triple Tiger.
Weight: 6.9g
First Clutch activates at start of battle. Slightly less self-destructive than Final Clutch because the Beyblade resists the destabilisation caused by the Engine Gear's activation, instead it breaks flower pattern and sometimes self KOs.
Has decent LAD compared to most Engine Gear BB's, however as it does not actually assist the LAD of Right Customize Gear (Free Shaft Version) + CEW Light Sharp combos and tends to get in the way, it is outclassed by Normal Base (Wolborg 4 Version) and Normal Base (Rock Bison Version)
Triangular protrusions cause minor recoil issues, but not overly terrible
The lightest Clutch-Equipped Engine Gear Blade Base (with First Clutch Base (Zeus Version) being the heaviest), though both Normal Base (Rock Bison Version) and Normal Base (Wolborg 4 Version) are lighter.
Not a useful part.
Overall
Hasbro unfortunately released this Beyblade without the Heavy Metal Core, causing enough fan complaints to add reasoning to its Q&A Page, explaining "We designed our Metal Driger top with an Engine Gear core, giving it superior speed and overall higher performance." - I will leave it up to the reader to determine how they feel about this comment but would generally advise buying Takara or SonoKong's version instead. While the Hasbro Version still has the useful Attack Ring, the rest of the Beyblade is not useful at all.
