Try if you can to at least get some circuits in every couple of weeks in the Winter, weekly in the Summer (unless flying weekly elsewhere)
Even after 25 years and nearly 500 hours I feel the benefit of at least 1/2 an hour or so in the circuit. The first one is usually not nearly as neat as the last, just makes the point to me that my 'currency' isn't what I thought it was.
Yes, I still get satisfaction from a well-flown circuit, even after all these years!
