Use in Smash Attack Customisation
Bull is severely outclassed by numerous other Wheels. Most of the little success it has had has been on mid-height Tracks: Bull T125RF is one such custom.
Spin Track: 125
Main article: Spin Track - 125
The 125 Spin Track is a midway between the 105 and the 145 Spin Tracks. Utilized in mid-height stamina combos, it is more difficult to destablize compared to 145 height stamina combos. It has declined in popularity as the choice mid-height track due to the release of gimmicked tracks of the same height, such as T125 and D125, which offer marginally more weight and balance capabilities.
Performance Tip: SF
Main article: Performance Tip - SF
SF is is a sharp tip with a flattened end. As a result, SF displays a combination of Attack qualities and Stamina qualities, moving in a semi-aggressive pattern. Because of this however, the two attributes are compromised, culminating in an average performance in both categories. It produces a movement pattern that, while is aggressive, is much slower than any Flat Performance Tip. The increased friction with the stadium floor due to the wider tip both increases its Defense and Stamina in comparison to a bottom similar to S or ES. However, it is in absolutely no competition with bottoms similar to WD for Stamina or RS for Defense. Semi-Flat is meant to be used in Balance type Beyblades, and as mentioned, exhibits aspects of several types, however it excels in none and thus is essentially useless.
SF's only mildly effective use is in Destabilizer customs where the low Spin Track used along with the balance of qualities allows the custom to destabilize the opposing Beyblade.
Unless used in a destabalizer combination, SF is highly outclassed.
The Bull Wheel was only briefly one of the top offensive choices for Wheels after Metal Fight Beyblade was released, and has since been outclassed severely. 125 Track variants in T125 and D125 have filled in the mid-height niche with additional gimmicks. SF is mediocre since it is outclassed by rubber Bottoms in Attack, and it is easily outspun by Stamina-based combos. There is absolutely no competitive reason to purchase this Beyblade.
