What do you mean by "absolute angle"? What is that relative to?

For measuring the angle of an arm, by all means those encoders are the best. For measuring the total rotation of the robot, a gyro coupled with the encoder inputs through a Kalman filter (or something of the sort) would be best. But it's hard to say without understanding what it is exactly you're trying to measure.
