I searched and found nothing, so I figured I could at least try and make this. Anyway, my Grand Cetus's original RS is now badly worn(I may add a pic some other time), and I realized that it moves more like I believe a RSF would instead of an RS. I have another one, but it's black and yellow and I want to keep the colors so I'm hesitant. And it actually has decreased defense, my other RS doing much better in terms of stamina as well. I don't really want to buy another one of the same Bey for one part, so I'm considering buying the white Grand Cetus. Anyway, what would you guys do?

Worn parts that significantly change their behavior from the intended use of the part violates the rules. You can't use them.
