I like AP a lot more than CP as well, docmani. However, as the GP stated, it's a good idea to do both unless you want to do academics. If you do private practice, especially in a smaller setting, you will inevitably be asked to be head of or director of a certain part of the lab that will require some CP training. In addition, if, as an AP/CP, you are just as qualified as an AP only candidate for a certain job, having the CP training as well will definately be an advantage and may lead to you getting the job over the AP only person.
