I strongly recommend the microtype package, which goes a long way
toward reducing hyphens and improving fit.
If that's the package I think it is, it actually places the terminal
character either a very small distance beyond or inside the actual right
margin. While under magnification we could see the jaggies, when actually
reading the page it appears straighter than otherwise.
Just another optical delusion.

Rich, You're talking about character protrusion, but the package does
font expansion and much more. Bottomline: text looks better. I can think
of few reasons not to use it.
