I don't have snap shackles on my main or on my furling genoa. Both sails' halyards are attached with shackles that have pins that screw in. The pins have never come loose. I have snap shackles on my spinnaker halyards, and more than once they have come undone when raising the spinnaker in heavy wind. Now I tape the snap shackle after closing it, to prevent it from coming open. When I used non-furling racing genoas, I used snap shackles on the halyards.
