A forty five degree angle makes the vectors of the straight and perpendicular motions equal (this should be obvious if you know basic trigonometry). That is why it is chosen by many teams as the angle for their rollers. It theoretically should make your strafing and forward motions equal. However... I do not think that's the case. There is just too much inefficiency in a mecanum drive system.

Changing the angles will change the vectors of the wheels. A smaller angle (assuming the maximum angle, 90 degrees, is just a roller mounted straight lengthwise) should theoretically give more strafing motion. Vice versa for a larger angle and forward/back motion.
