I'm interested in this, but my understanding about currency is that it is often club or group based,some want less than 28 days between flights,other 90 days.
If you dont meet this ,you need a check flight with an instructor or group member
From the official point,I think you need 12 hours in second year and think there is also some official requirement of currency before taking passengers.
This is all off the top of my head so stand to be corrected.
