Driving Straight is definitely possible with omnis. Arc turning with two back omni can cause your back two omni wheels to fishtail moderately making the robot more difficult to drive. FRC#494 in 2006 used omnis in the corners instead of two omnis on the back side to help control fishtailing. Read the full report on page 160 of the 2006 FIRST Robotics Book.
