if you want goo experience fly solo or with other pilots (non-instructors) real IMC in long cross-countries. dont need to burn holes in the sky
An adf approach in moderate turbulence and IMC, thats good experience
you can also try basic aerobatics, immelmans, loopings, spins, lots of fun. you dont need inverted oil system for this.
Many airline pilots do not have polished adf skills. Just remember the crash in croatia (dubrovnik) involving an USAF business jet. Those guys got lost on their adf approach.
It does not mean you will be hired because its a different matter, but you will be a better pilot, able to handle most situations
