Just to play devils advocate, you don't really have to "learn pitch", it is done in the same manner. Meaning, you raise throttle to increase pitch, or you raise throttle to increase head speed. Yes, a fixed pitch is way more stable, but if you are flying CP already, it is definitely a step backwards to go FP. The controls are the same for both. But I do understand where you are coming from and would be interested in hearing your experience if you do try this.
