Maintaining your IFR currency isn't that hard. Just fly and log in actual or simulated conditions six instrument approaches, "holding procedures and tasks" and "intercepting and tracking" electronic courses within the preceding six months, and you're golden. Even if you find yourself slightly out of currency in the 11th month, you can go out with a safety pilot and fly the requisite approaches/holds/intercepts, regaining your ability to legally file and fly IFR.
