Best drywall cornering

Q: What's the best type of corner bead to use when drywalling? I've hired a crew to install drywall and they're planning to use corner beads with paper that runs along each side. Is this better than the old all-metal corners?

A: There are a few different types of drywall corners on the market these days, some of which (I know from experience) are stronger than the old all-metal types. These old-style corners work okay, but they are prone to denting and cracking. Also, paint chips off them fairly easily because they come to a relatively sharp point.

A company called Trim Tex manufactures my current favourite corner bead. It includes a large-diameter curve made entirely of plastic. You fasten it to drywalled corners with spray-on contact cement. Besides being surprisingly tough, the large curved surface resist paint chips quite well.
