[Unanswered]  Custom Beyblade made from scratch

So I'm making an X Beyblade with a 3 bladed design (each blade is slightly hollow with air vents on the outside) with the blades being able to protrude at high spin to create a smash attack shape, and then the blades tuck in at low spin to make a round (defense) shape. What balance combo would be good for it? (I say "it" because I haven't come up with a name yet) I think that combos like 3-60GP or 9-60U would be good for it, giving it that attack and defend transition during battle. In case you are wondering, the blades contain a reverse spring mechanism, with the springs being able to retract the blades easily.

This part of the Beyblade would be the least important, but what color should I paint the 3 blades, the avatar sticker piece, and plastic parts? (I think that the blades should be dark metalflake purple, the avatar sticker piece crimson, and the plastic is colorless clear plastic, so if you guys want the plastic to be a different color, I can send it back to JLC3DP to have an actual color for it.

The avatar I'm thinking of making is a spartan, with the concept of a purple-and-red spartan appearing to pierce the actual sticker. The idea really fits due to the nature of a spartan's attack and defend tactics in some cases. If you have any design ideas that make the bey better at its job or look better, then tell me in the replies section.
Woah cool! Maybe I'll suggest the stock combo for it to be 3-60P. 3-60 is for matching the 3-bladed design and point has good attack and defense.
