Wind ahead of beam, main up first, if behind beam, jib first - the old timers thought. Then balance sails to conditions.
They also said, don't use single sail unless you want to be laugher at at the club!

Always, l mean always use boom preventer if wind behind beam, no matter what.
Downwind, get up second jib goosewinged, scandalize main or drop it, unless using spinnaker. Especially on a boat prone to broach.
Those were the basics years ago.
