Hmm, well, drywall screws worked for me. All of these worked for me (yes, that's a bag o' generic drywall screws, so old that I don't know what brand they'd be). I got the green box at the Despot.

Yes, you have a choice as to which one you want to use. Choose the one that is more comfortable for you. The smaller one is good for me.

They can be, but you have to be careful to go just far enough in. If you don't want to take the chance, a round head is fine too.
