Well if you think about it, MFB had this problem too, as most red track and bottom were labelled Balance Types, blue was Attack, White/Grey/Black was defense and Yellow/orange was stamina, of course there are a few exceptions but not counting random boosters, yeah.
Exceptions I can think of from the top of my head are:
The original BD145DS had a black track and bottom for a stamina setting rather than yellow/orange.
D125B from Rock Orso and S130RB were both green although a very dark green.

is blue instead of red for a balance type.
I know some might bring up 145WD from Earth Aquila and WA130HF from Thermal Lacerta, but WA130HF was more of an attack setup thrown into a balance type and 145WD I believe was a defense setup.

No I don't plan on doing more yet.
I should probably go back to making fan custom Zero G beyblade concepts again
