it would be a good idea to use the sprockets to add another gear reduction between the CIMple box and the wheels.
You might want to think about changing all 4 wheels to omniwheels at this point, since changing just 2 will give you a somewhat funky drive (turning point very close to the non-omni wheels).
The obvious disadvantage is that you can not resist being pushed sideways.
you should think about your game strategy and decide which change is best for you.
summarizing:
- change the sprockets so you get more gear reduction between the cimple box and the wheel.
- change 2 or 4 of your wheels to omni wheels.
Good luck and keep us posted if you need help.

At the regional, be sure to bring a camera and take pictures of drivetrains and mechanisms you find interesting, veteran teams a fountain of inspiration and knowledge for rookies!
