- 2x 6" AM performance wheels
- ~1.5" compression

We're getting pretty good distance out of this setup, shooting from the key at about 70% drive on the motors.
The 6" actually worked a little bit better then the 4", we switched to the 4" on Saturday morning to try it and it we actually took a step back. We had a mentor from the GatorZillas come over and he said we had way to much compression early, as in when the ball first hits, and not enough on exit; this was with the 6" in. So we tried switching to a smaller wheel to try to counter that. We cant just turn the hood around, otherwise we would have done that.

The 6" wheel is the AM white plastic hard wheel, and the 4" is the plastic one that was on the FIRST Choice list.
