Hanging things on metal studs
Living in South Florida I know exactly what you mean about the metal studs. What has worked for me is starting out with a very small drill bit and moving up to the size you finally need. The best screws to me are drywall screws if you can stand the black appearance and the head sticking out a bit. You can usually start them out with a whack of a hammer and don't even need to drill. Good luck.
