I'm currently watching swiftmfb's bb10 repro review video, which he buy from Ali express, chekout on he's youtube channel
And i found burst standard mein ridge same as repro bb10, and burst standard don't have secondary ridge at same position like bb10, secondary ridge place on little bit higher portion, so you can't do flower pattern like in original bb10, burst standard 60% for stamina type beyblade's
Trying flower patterns with different weight beyblades
1 - Light weight flower pattern
2 - Heavy weight flower pattern
3 - Super heavy weight flower pattern
Need to littlebit skill enough to launch like this,
Some little bit difference you can notice easily.
