I've gotten rid of all my ball clasps that have the fishhook tongue. I've replaced them all with either balls that screw (that sounds dirtier than it is), although I only use those as decorative disco balls and never unscrew them. Or with orbit clasps, which I love.
The orbit clasp is secure, and it makes the necklace sit well at the back of the neck. It's also great when worn in front because you can hang a pendant off it. And it's decorative enough that you can string several necklaces together and have the clasp show, and it looks like cool links.
