Good call.
Too many pilots look at the 90 day rule or club currency rules in the wrong way - they think that they are current up to the limit. One member of my group is like that, and flies just enough to stay clear of checks. But when I fly with him I am horrified at his lack of airmanship.
If you feel out of currency, even though by the LASOR or club rules you are still OK, then there is no shame in using an instructor.
