Only a single one, although I slightly modified the original Pegasis and Bull articles.
Pegasis was labeled as "currently the best defense wheel to date", and bull as the best attack.
Clear Wheel: Pegasis
The original release of Pegasis is a blue transparent plastic wheel. The edges of the Clear Wheel are shaped in a wing like pattern, each ending in a pointed ‘head’ shape, representing the body form of Pegasis, the symbol its design is influenced by.
Metal Wheel: Storm
The main shape of Storm consists of three wing like forms, which are used for considerable attack. The wheel is a cheaper alternative for that of Quetzalcoatl, and is considered by many to be inferior to the Lightning metal wheel.
Storm Pegasis 100RF however is still a top tier attack combo, due to a decent level of smash attack ability from the Storm wheel. The slightly jagged end of each of the three wing like forms that Storm consists of are well suited for smash. Quetzalcoatl how ever is still a far more consistent attack wheel.
Use in Attack Customization
Storm has proven itself as a decent Attack wheel, earning itself a position as a first tier part.
Storm (as is the case with the majority of Attack wheels), works best on a lower track, preferably 90 or 100.
Storm Pegasis 90/100RF would be considered as the best possible combination for Storm.
Track: 105
105 is the third shortest Track to be released, and has been released multiple times. Although 90 and 100 have been proven to be better options for most Attack types, 105 is still a decent option if the aforementioned Tracks are unavailable.
Bottom: Rubber Flat
RF, as its name implies has a flat, hard rubber tip, with a small indentation on the base of the tip. Its tip has just about the same width as WF, and is the second highest Bottom next to HF/S, which makes the shortest Track, 90, particularly useful in combination with this part.
By using its wide surface area and rubber material, the Bottom has a large amount of traction against the stadium floor, resulting in a such a fast and powerful attack pattern that it often renders itself useless by self-KOing the Beyblade it is being used on. Part of the blame for this problem can be put on the poor Tornado Ridge of the Attack Stadium, but the fact remains that RF was designed long after the release of the Attack Stadium, and should be able to maintain itself within it. To alleviate this problem it is recommended that you never use a brand new RF in any sort of competitive situation, as it's likelihood of self-KOing is much higher; wear it down a little with some practice battles first. When this is done, the rapid movement of RF may subside slightly, but it becomes more controllable, and thus, more useful.
The use of rubber and the friction it creates with the stadium floor does lower its Stamina in comparison to plastic flat tips such as F and WF, but this is usually not a problem as an Attack types goal is to KO the other Beyblade, and it also helps reduce the recoil of violent Wheels such as Sagittario.
Mold Variations
RF has two different molds. The original TAKARA-TOMY manufactured RF, and then the SonoKong manufactured RF variant. Some of the TAKARA-TOMY RFs tend to spin around freely when twisted between fingers, due to the circular nature of the rubber that held the tip itself into place. However this problem was rectified by the SonoKong mold which flattened two opposite sides of the rubber that holds the tip itself into the plastic section of the Bottom itself. The flattened sides make it impossible to spin the tip freely, thus solving the problem.
The performance difference between the two molds is negligible, but it is likely that the SonoKong mode would be more sturdy by not spinning around.
Use in Attack Customization
RF is considered by many to be the best Attack Bottom currently available, and is currently in use for all three top-tier Attack customs: Quetzalcoatl 90RF, MF Lightning L Drago CH120RF, and Storm Pegasis 100RF.
Use in Defense Customization
After heavy use, RFs tend to wear down, and their movement is reduced significantly. When this is the case, the traction created by the rubber can be useful to keep the blade from being knocked from the stadium. RF can be used effectively in the defense customization MF Libra C145RF.
Use in Balance Customization
RF has found use in a very specific Balance customization; in fact, it is really the only competitively viable Balance customization at this point in time. The custom is Libra CH120RF. Here is how it performs against the current staple customs:
* Versus Virgo DF145D -- use 120 height
Even though Libra is the heaviest Wheel ever created, because it's weight is focused around the outside, it is still quite agile with RF. On it's own, Libra is not a very effective Smash Attack Wheel, but it's weight distribution in combination with the fast moving RF allow it to achieve an astonishing 90% win rate against Virgo DF145D. 120 height must be used in order for the Metal Wheels to make contact or it won't work.
* Versus Quetzalcoatl 90RF -- use 145 height
By switching to 145 height, the Track will absorb all of the hits dealt by Quetzalcoatl. The weight of Libra combined with the grip of RF give it enough defense to withstand most attacks, and again, the win rate is 90%.
* Versus MF Libra C145WB -- use 120 height
The win ratio against the top tier Defense combo isn't that great -- only about 60% -- but this still isn't bad, considering how strong it is against the other two types. If you can avoid using this combo against Defense-types, you should, but if you're forced into that situation you can win with a perfect shot and a little luck.
To effectively use this custom, you absolutely must be able to perform Sliding Shoot because the window for landing a successful attack is much smaller than with other Storm or Quetzalcoatl-based Attackers. A skilled Blader can use this customization as an answer to almost anything that is thrown at them.

Overall
Storm is a top-tier Attack type Wheel, and 105 does have its uses in the absence of 90 and 100, but RF is without a doubt what makes this an essential buy for every competitive Blader. The Bottom can be unstable and hard to control, but if it is worn down a little and the proper skill is applied, it can be deadly. Every Blader should own multiples of this Beyblade.
