I don't think using Dunlops would have cured the problem unless their screws are somehow unbreakable.
Here's what happened... Did a song and a half soundcheck... Everything is cool. Opening bands play... Grab bass... tune up... on stage and get the go ahead from the sound guy... Guitar player starts talking on the mic... I'm getting myself ready to start the first song, and the bass starts traveling towards the floor. The screw sheered clean off while just standing there.
Now as for Dunlops... Guitar player uses them as he prefers them to Schallers, BUT during a show one time the C shaped "snap ring clip" on the his Dunlops had apparently worn just enough where it slipped off and sent his Gibson to the floor, mid song snapping off the high E string tuner.
Glad he had a backup too.
