Knockback is a term refering to how hard or far a bey travels after getting hit. It often causes Outspins, Knockouts, and if you are using burst beyblades, bursting. Unlike recoil, knockback is determined with one beyblade, the one getting hit. Large ammounts of knockback is usually wielded by Smash Attack, Force smash, or Upper attack beys, but on certain occasions, Defense or stamina types can cause a big ammount of knockback with their heavy design. Knockback is determined by these factors:

-The weight of the bey attacking
-The weight of the bey getting hit
-How fast the attacking bey is moving
-How fast the defending bey is moving
-How round the attacker is
-How round the defender is

The heavier the attacker is than the defender, more knockback will be produced.

What about the layer weights for judgement Spriggan and zwei Spriggan? Also, I'm not sure left spin chips can be used on imperial base.

I'm not sure if this is going to be approved into a page on the Wiki, but I'd like to point out a few things in case it does. First of all, Zephyr is primarily used for Tornado Stalling in Burst Classic, and the tactic has already been outclassed in Standard for quite a while now. Second of all, low-hanging frames are not good on Attack Types (especially with plastic Drivers) because of the scraping issue when trying to do an angled launch. Third, Spiral' isn't very good unless the opponent chooses an opposite-spin combo that goes on the ridge often, but even then Quick' would do a batter job at that with a flat launch. A fourth issue is that the article could be more useful if it was about KO Attackers or if it was implemented into an article about Attack Type combos in general. The final thing is that you might want to add on that Drivers that create more friction with the Stadium floor allow a combo to knock out its opponents more easily while making it harder for it to get knocked out.

Made Revisons adding Possible MFB combos. If these combos are inaccurate, please tell me what are good knockback MFB combos.
