Aeros is a great idea. As an instructor in both i find that even at low hours a student can benefit all round in aircraft handling. You can certainly develop a "feel" for the aircraft quicker and so aeros will help in your PPL course. Understanding the aircrafts envelope and not being afraid that it will fall out of the sky if you turn at an AOB of more than 15 degrees has helped several of our more 'nervous' students.
Enjoy guys!
