I recommend you convert your Zephyr to a dual deploy bird by adding an ebay and a payload bay. This is a pretty simple conversion. Fly it a few times on H & I motors to ensure you got the build right and your dual deploy system works, then use that rocket to get your level 2 on a small J. I have two Zephyrs and converted both of them to dual deploy and fly them on J's frequently. It is a great bird and the process of converting it to dual deploy will give you some great level 2 skills while providing you with a rocket you can test safely with Level 1 motors until you are sure it is good. Then, when you fly it for your Level 2, it will just be another launch instead of an anxiety producing experience.

I also have a PML AMRAAM. Great rocket as well. However, it is not as simple to build due to the quantum tubes and piston eject system. Those components add complexity. Also, unless you are planning to modify the AMRAAM 3 or use a Jolly Logic chute release, Rocksim is showing that an PML AMRAAM 3 will go to about 5000 feet on even the smallest J motor. That would be a pretty high Level 2 flight and may cause a very long walk or even a lost rocket on a single deploy flight.
My dual deploy Zephyr flies to less than 700 feet on a small J and bumping that up bit gives you a nice low and slow dual deploy flight on cert day. I would aim for a nice 1200 foot flight with mains opening around 500.
