We found the same to be true. We also found that it is very difficult to do a pure forward/backward, left/right, or cw/ccw twist and the driver would often do multiple moves at once unwittingly. For that reason, we have a 2-stick setup - one for forward and turning, one for strafing. Intuitive for laypeople, and workable in competition.
