I fully agree with Genghis on this one.
Flying at night is fantastic! The air is usually calm, visibility excellant and little traffic on the radio. Other a/c are easier to see.
You don't need a practical reason, just spend the money and fill yer boots!
It will as likely only take you 5 hours to do. If you want for the summer though do it now before the nights start even later.
Best of luck
