Feel free to correct me if im wrong, but thats what we have always done.
Definitely. Unless you want to have ~2" diameter wheels (in which case, the CIM would be the part touching the ground), you should really consider a reduction. My experience has been that an additional reduction in the ballpark of 4:1 (for a 7.5" diameter wheel) provides sufficient torque in 1st gear (for pushing/wheel slip), and plenty of speed in 2nd and 3rd.
