Final Clutch Base (Desert Sphinxer Version)
Blade Base: Final Clutch Base (Desert Sphinxer Version)
Very compact Final Clutch Base (being the same width as Normal Base (Wolborg 4 Version) but being a lot deeper.
Final Clutch does occasionally cause a late battle offensive push with flat tips, but generally the Beyblade is too low on rotational energy at this point to do anything of note, and with ARs that might help this such as Square Edge not being effective on such tall setups, this is generally ineffectual.
Nonetheless, this does make them more effective than First Clutch Bases. However, Normal Bases tend to be better simply for being less bulky, even though they generally don't make use of the Engine Gear mechanic.
Upper ring is perfectly circular, and while the triangle details do have some recoil, most Final Clutch Bases are worse. In addition, these details are mostly protected by Circle Survivor.
Arguably the best choice for Circle Survivor Defense as a result of these characteristics, being almost 2g heavier than Normal Base (Wolborg 4 Version) and Normal Base (Rock Bison Version) while being no easier for opponents to hit and increasing the compact-like weight distribution of the rest of the combo.
The fact it comes with a suitable engine gear (Right Engine Gear (Mystery Cutter)) for use with itself and Circle Survivor is a bonus.
This said, the performance increase over the two Normal Bases is fairly minor as the combination already has incredibly strong defense at that weight, thus it isn't a must have by any means, especially given its rarity.
