Thanks to everyone who has helped me out here!! Some valuable knowledge has been gained!
FFF and Fuji, I would admitt yes, I realised a bit of a void was left after I got my rating. I understood what was required to pass the IMC test, and I would also like to say that under the guidence of my instructor I was prepared to do this to a good standard. Practicing in the aircraft, along with the use of Flight Sim (plus the added benefit of my ATPL Radio Nav Textbooks) helped me get to grasp with the IMC course and impress the examiner enough to pass the skill test.
Whilst I would never look to intentionally use my rating in anger, I never actually know when it may or could be called upon. It has given me a little bit more confidence and piece of mind in my flying and has provided me with an appreciation for what is involved in the IR course (which I intend embark upon very soon). However as rightly noted, I didn't really have the knowledge of what a private pilot is entitled to with the IMC!
I am looking forward to investing a little time in refreshing my skills with an Instructor at my local club. It won't do any harm! Thanks once again
