In answer to your question.....
I would strongly endorse acquiring the IMC Rating. The reasons have largely been outlined.
My comment concerns the training itself. When I started I had a bit of difficulty visualising the 3d situation and became confused as to which leg, turn etc I was on. After about 5hrs I was going to bin it as too much like hard work; it was after one particular exercise that everything came together and the realisation that I was not incompetent came as a relief. If you start, stick with it (like you did for the PPL) it will come good.
The best bit comes with applying the theory....I was blown away the first time I used the rating in anger ......the theory worked!!!!!!!!!!!!!!!!!!!!!!!
