Bistool
Weight: 3.1g (Mold 1) | 3.3g (Mold 2)
Right Spin only (which is unfortunate, as if it were Left Spin capable it would be the best Zombie AR in the game).
Small size, very close to Wide Defense/Wide Survivor in width, and relatively lightweight.
Excellently balanced and rather edge-distributed, thus excellent solo spin times (though not as much as Gyro Defense)
Some recoil problems unless covered by Wide Defense/Wide Survivor, and even then it remains an issue on lower bases or when tilting.
Two molds – the second is more reinforced to prevent breakage of the wing tips, which the first mold is very prone to.
Mold One performs slightly better in all applications, as it has lower recoil and slightly better weight distribution. However, it should not be used without a Weight Disk which protects the wing tips, as it is very fragile.
Mold Two is slightly heavier due to reinforcements, but performs marginally poorer due to the slightly worse weight distribution.
Best used with Wide Defense or Wide Survivor to reduce recoil/breakage.
Very good for Right Spin Stamina combos and Zombies, as well as Circle Survivor Defense combos utilising Wide Defense.
Can be used for compacts, being a more aggressive option than the mainstays, though Tiger Defenser and War Lion are generally superior choices as the minor bump to offense isn't worth the additional recoil (and Tiger Defenser is not much less effective offensively anyway), nonetheless Wing Cross is a competitive choice for this type, with the usual Mold 1 fragility caveats.
Weight: 15.3g
The most compact weight distribution of any weight disk.
It is worth noting that there is quite a broad range of weights for this Weight Disk, which one should be wary of.
The large corners of its shape result in some recoil when hit, though its compact weight distribution provides some protection against this.
Ten Heavy outclasses it slightly in all aspects of performance due to heavier weight, lower recoil, and Eight Heavy is marginally heavier, with a slightly less compact distribution making it a viable alternative.
Fairly competitive in Compacts and Traditional Upper Attack and a backup choice for Weight-Based Defense and Semi Flat Base Stamina Combos.
Blade Base: Semi-Flat Base
Weight: 7.2g
4 Layer System Base with built in Right Spin Gear.
Lightweight
Usable Life After Death
A very stable tip with good stability and survival, making it a good Stamina part.
Commonly used in Survival combos with Ten Balance (as Wide Defense and Wide Survivor have issues with rotational recoil and stability on this base), these are best called Semi Flat Base Stamina Combinations, especially as Heavy-Series Weight Disks are also an option, the most famous of which is 10bBistool.
Outclassed by Zombie Base/SG setups, but still a reasonable option in most tournament situations as Semi Flat Base Stamina Combinations are able to beat most Tourney Filler. However, they lose to almost all competitive combinations and as such do not deserve the accolades they have received over the years.
There is an alternative mold used by certain Takara releases (notably Roller Defenser) which has a thinner tip, making it slightly less aggressive and providing slightly more survival. The difference is largely negligible in battle, however.
Overall
The Attack Ring is excellent (though you have to choose between breakage issues or slightly poorer performance), and the Base is decent if outclassed, making for a decent Beyblade even uncustomized, but don't buy into the hype about 10bBistool, which has inflated prices somewhat - it's fine as a stamina combo, but greatly overrated and holds up poorly against top-tier combinations.
