WHAT TO BUY

ok, this is the section on what to buy in beyblades to become any good, i will try and keep this as updated as possible but this list wont contain everything you should buy, look around the W.B.O for all the information you need.
ATTACK:
lightning L-drago:  good all over but mainly it's wheel as it's the best attack wheel available. all you need is a rubber flat tip to make this bey almost perfect. also the takara tomy starter of this comes with a left string launcher, so try getting that one.
storm pegasis: now don't go saying this is the best bey, this beyblade is only realy good for it's tip, and is the only reason why you should get multiples of this bey. the tip gets worn quickly so try to get as many as possible and just sell the rest of the parts, or keep them for collection purposes. although, it's not terrible uncustomized, it's metal wheel used to be great and its track is used as a replacement for 100/90/85.
dark gasher/cancer: now this bey is only good for it's track, CH120. it's height change allows you to fully controll LL-drago CH120RF, all you need to do is keep it's on CH120 mode for low tracks and CH145 mode for high tracks like 145, th170 and most importantly, 230. the rest of the bey is no good. also try to get takara tomy's version, it's stronger and has a better lock, Hasbro's just changes mode all the time.
Vulcan Horus: this is good for it's amazing attack value in it's wheel. it's known to be the best right spin attack wheel, but only if you have the right clear wheel, witch i forgot witch one that is. it's other parts aren't good for attack but good for other types.
beat lynx: ok, now this bey is still in the testing but it's sad that it's wheel is just like vulcan, super smash attack. it's track is also in testing but it's highest mode might be close to 230, but not good for attack, yet. it's tip is also for stamina. if you got the right pieces already, this bey can be used well.
gravity persious: this is also like vulcan, super smash attack in it's metal wheel and stamina in it's track and tip. not only does it have this feature, but it goes both left and right, with a launcher that comes with both spins. good as a starter bey as it allows you to get used to both spin directions.
Quetzalcoatl: now this bey is good for it's track and tip, but it's wheel has been out classed. it's track is 90, the second lowest track, and wide flat witch is used in the combo L-drago 100WF for being the safest destabilizer. of cause, this bey is expensive for being limited edition, you are better off getting the attack/balance parts set, thats how i got mine.
mercury Anubis: this is like a better version of Quetzalcoatl, with a better track and tip but worse wheel. it's also obtained the same way so it's the same cost. it's a must have.
stamina:
earth eagle: now this is probably the best uncustomized bey, only rivaled by hell kerbecks. it's metal wheel is good for stamina and defense by it's weight and smoothness. it's track is 145 is basic but good for stamina and it's tip, WD, is the best stamina tip out. this is a must have.
hell kerbecks: as i said above, this is close to being the best uncustom bey, failed only by it's tip. the clear wheel is heavy and three sided, great for wheels like ray and hell. it's metal wheel is great stamina and decent in attack. it's track is probably the best track ever, used in stamina, defense, attack and even balance. it's tip is the only bad part, as it fails to many other stamina tips. another must have bey.
flame byxis: king of all stamina bey's, it has the highest track ever, with a bonus decent metal wheel for stamina and the best stamina tip with a strong purple color. it's another contender to being the best uncustom bey, but flame and it's clear wheel are parts that make it not the best uncustom. it's still a must have bey.
basalt horogium: this has the heaviest metal wheel ever, witch maximizes defense but also makes it decent for stamina. it's track and tip are the same as earth eagle so it's almost a better copy of eagle, if the metal wheel with the track and tip negate each other. yet another must have.

defense:
basalt horogium: see above.
libra: now this is an outclassed bey, but it used to be so good it was banned from official takara tomy tournaments and W.B.O tournaments because of it's weight. it's still decent in the combo MF libra 100CS and a good replacement for basalt in MF libra230CS. not a true must have but decent.
ray unicorno: this is gotten only for it's tip, the most balance tip CS. it's got stamina, defense and a bit of attack if shot on an angle. it's only good for it's tip but it's still a must have.
dark bull (takara tomy only): this is only for it's clear wheel, so don't just go buy the bey as soon as possible. it's the heaviest clear wheel by takara tomy and it's balanced. again, it's not a must have, but helpful.

balence:
hell kerbecks: see above.
libra: see above.

gear:
string launcher: this is the currently the best launcher out, it makes beys spin strongly while having control. people used to rip cords normally can't use these well strangely but i got the hang of them instantly. a must have for all types of beys.
the rev up launcher: now this launcher is the hardest launcher to control, I'm one of the only people in the world that use it perfectly. it's also the most powerful launcher ever, but terrible for heavy beys or attack types, as heavy beys fall off to quickly and attack types self KO. only a few people can master this launcher, but those who do can get stamina and defense types spinning faster than ever.
grip: any grip is a good grip, but the more comfortable the grip is the better, so find the grip thats best for you. some don't even need a grip.
light launcher 2: this is weaker than the string launcher but easier to control than other launchers and still has the feeling of a rip cord launcher while being stronger than the rip cord launcher that Hasbro and takara tomy made (takara tomy calls their rip cord launcher a light launcher 1). god gear for those not used to string launchers.
metal faces: not realy gear, but an actual part. it's need for many different combos and you get 2 in a pack. you also get a cool tool with face bolt holders for your spare face bolts. there are many weights, the heavier the better for attack and defense and the lighter face is good for stamina. it's a must have piece of gear.
takara tomy stadiums: all but the square stadium are good for training for tournaments. the takara tomy attack stadium is the best. the stadiums allowed in W.B.O tournaments are the balance, super attack and attack. those the the must buy stadiums.

and thats the list so far. i will add more later and as more beys get released. now for the not to buy.

beys:
any beyblade with the dark wheel excluding dark cancer. any light wheel bey and killer is another sign it's a crap bey. metal wheels are normally the mark of a good or bad bey, but you still have to consider the other parts.

gear: never ever buy the wind and shoot launcher or the duosion launcher, they are the worst launchers ever. also don't buy any Hasbro stadium unless you have no stadium, but if you have to, do not get the pegasis thunder whip, super vortex (good for the beys though) or the portable stadium. those are the worst stadiums.

follow this guide and you will become a champ in no time.
