The IR would only really come in handy if you've got somewhere on the continent to go to regularly.
You're only 22 and already own an aircraft, so I'm guessing that a family or friend's home in Switzerland , Spain, Southern France, Italy etc might be common destinations, in which case it'll be very useful to have IR.
Or perhaps regular business trips to these places might feature in your future?
Otherwise, aerobatics might well be the next step for you young man....
