Hasbro,
Theres not a whole lot in the way of design that I could add to, the original beyblades were just fine when it came to their quality. All I can really ask when it come to MFB's is just to maintain the standard of quality, and try not to alter Takara's designs too much.
Also, if the BBA is to become active again and tournaments are held, I would reccommend making two age classes rather than simply cutting off at 15 and only having exhibitions for those older, excluding them from championship competition. An 8/10-15 class, and a 16 and older class. Although the older class would likely be significantly smaller, it seems to be a little foolish to exclude the age range that has more monetary value, and there will likely be fans of the earlier beyblades that have aged and may still be interested. If the older class dosen't seem promising after giving it some time, give it the axe, but I don't see a reason to not give it a chance and see how it goes.
I'm looking foreward to seeing what Hasbro has in store for us in 2010.
(First real post here, but I've been lurking for a while, hope I didn't embarrass myself. lol)
A good champion is someone who gets up when he can't.
