Since you guys are a rookie team, I'll give you a hint.... Mount the wheel directly on the CIM and add 'squish' on the sides to increase the friction. The greater the friction, the better they fly! We used
Rough Top (blue stuff) when we were prototyping. I personally suggest you do not use rough top, as it tares up the frisbees pretty easily (field damage), but instead search AM & online for something similar that is 'squishy'
Hope this helps your team out, and good luck!
