I'm finishing off my basement as a dedicated home theater, and I want to avoid building a soffit around my toilet plumbing. My floor joists are 2x8, and I have about a 4-1/2' run to the main stack. I'll be replacing the copper elbow that presently juts well below the joists.

What are the merits of using a spigot closet bend vs. a 45 closet flange with a street 45?

On a side note, to make the degree symbol you can use either use Alt+0176 (on the number pad only) or you can insert the symbol using Microsoft character map.
