If you are serious about being a progressive and professional pilot, don't pay for ICUS.
I too thought that the Vortex thing sounded like a good idea when I was starting out, but when you get into the world of commercial aviation, you will realise that you were just increasing the profit margin for flights that have already been funded.
Never pay to operate any aircraft that is already making bank for the company, consider yourself, your enthusiasm and your time as the asset you are presenting to a potential employer, not your cash.
