Hey Bladers!Ever wondered what a Beyblade combination is made out of and how to choose parts for a Combination ?Follow the guide below. 1. Always look for Burst layers that are not used very much i.e. Have unworn Teethworn teeth are more prone to bursting, which may make you loose in the event even if you have selected a very good combo.2. The layers must never be dented or chipped off in a visible manner , this makes that layer highly unbalanced and could damage other beys too.3. The weight disc must never be used if Rusted, this will make the disc get stuck and unable to burst. Always keep your discs in an air tight enclosure\Box to save them from rusting.4.The weight disc always have stars made under them, the more the number of stars imply higher the precision of that disc. These range from 1 to 4 . So before choosing a disc always look for the number of stars on that disc.5. Drivers must always be used with Semi worn or New condition to give you more edge in the fight, this has an exception to Variable driver which works best if it is worn.More hints will be updated by @renidage , @Adarsh Abhinav , @Blader ZX , @FIREFIRE CPB , @snidmist .
