Here is a beywiki draft about the S series, I wanted to do a beywiki article about it since I have (or had) most of these tips.

The s series is a series of bottoms that have a fine tips, they mostly feature good capability in stamina combo's however they (arguably) wear down very easily.

There are quite alot of S series tips, here is some info about each of them:

S: Sharp
The Sharp Bottom offers very little movement and as such provides no attack potential. The pointed tip allows for very little friction between the Bottom and the stadium surface, which helps prevent the loss of spin velocity. However, due to the fine nature of the tip, the Bottom is easily knocked off balance, and hence is outclassed by superior alternatives such as D, WD, and SD.

BS: Ball Sharp
BS' performance is quite similar to that of S. BS offers very little movement and as such gives no Attack potential. The pointed tip allows for very little friction between the Bottom and the stadium surface, which helps prevent the loss of spin velocity. BS has decent Stamina, but because the tip is so fine, it experiences balance issues like S does however does provide a bit of defence. WD, D, and SD are much better choices.
There have been two releases of bs by hasbro, the first version was a ball tip with a sharp tip to it, however (as with many of the metal fusion beyblades) the could break very easily, so in when version two was presented in metal masters it was reinforced along with r2f,cs,hf,f,b,es,rs,wd and wb

ES: Eternal Sharp
Eternal Sharp features a free-spinning tip attached to a metal shaft which is held by the Bottom. The part was one of the most heavily anticipated parts in the MFB lineup when first announced, but ES is actually a hugely disappointing part in terms of performance.

Firstly, ES lacks a metal bearing, which would significantly reduce the friction between the free-spinning tip and the rest of the Bottom. All of the best free-spinning tips, notably Bearing Core, had NSK Shield bearings which allowed unhindered spin.

Secondly, the tip shape of ES is not conducive to optimum Stamina; the sharp nature of the Bottom means it is easily destabilized. As all Sharp tips do, Eternal Sharp also has trouble regaining balance, hence making this a poor choice for Stamina. That said, ES still remains superior to BS and S as Stamina Bottoms.

FS: Flat Sharp
FS features a flat tip with a smaller, sharper tip in the centre. As a result, when launched at a straight angle, the Beyblade spins on this sharp tip, with very little movement. However, when tilted, either from the contact of an opposing Beyblade or from the launch, the Bottom moves in an offensive pattern. However, it suffers from the same problems as other Balance Bottoms, in that the two qualities are compromised, resulting in mediocre performance in both fields.

RS: Rubber Sharp
As its name suggests, RS is a sharp tip made of rubber, and with that, all of the problems sharp tips are known for, as well as the poor Stamina of rubber-based bottoms, and their tendency to wear down after extensive use, are brought along with it. However, RS's primary purpose is to counteract Attack customizations. The high friction of the rubber, along with the lack of movement due to the sharp tip make it incredibly difficult to move, and thus, KO.

RS does seem to have difficulty sometimes outlasting left-spinning customs, but against right-spin Attack customs, despite it's poor balance and Stamina, it is able to effectively neutralize them.

MS: metal sharp
MS is a bottom with a mettalic point, it seems to be able to have a mean solo spin time of 2:01.4 (M:Ms), it is very high for a bottom and can become unbalanced easily, however the metal reduces the friction between the arena floor and the bottom.

I hope you like it, this is my first draft and I hope that I didn't do too bad. , I used a few existing articles about the tips edited them and brought them together in this article.

Signature was too based. Read the rules.

Such an article is not really needed. Each Beyblade article will have what it requires, and someone already made a page to put all the Bottom descriptions together, so that would be more adequate.
