I find that the AR on Master Dragoon, Kid Dragoon, Dranzer GT etc. can potentially become Metal Fusion Wheels with a more evened out ratio of size and weight. If they do make this AR then it would look awesome.
If it's possible, I think the plastic on attack beyblades like the R2F is not strong enough. The rubber is very durable, but the plastic can't really take the strong impact, some times I'm afraid that it will break. I hope they strengthen the plastic up in the 3rd MFB beyblades (BigBang Pegasis).
I would
REALLY want a WRF (Wide Rubber Flat) that can mimic the movement pattern of Dragoon MS or MSUV. RF has a diameter of 0.5cm = 1.57cm2. I don't know about the RC for DGMS, but I hope they replicate it.
