There is much confusion over whether you will get hrs off the IR so if that is why your doing it bewary!!
I did mine however and am VERY glad I did as it has come in handy once or twice already during flying and also during my ATPL course (as i had a better understanding of the radio nav equipment etc)
Its a worth while license to get as it WILL and there is no doubt about this help towards your ability during your IR whether or not it helps towards the hours and in my opinion (not that it means much) it helps to making you a safer pilot
