To answer Bill's question; I rarely used #14 when I was doing residential. Most of my jobs were large custom homes with long home runs. I stuck to 12-2 for voltage drop as much as the convenience of only dealing with one wire size. Box fill wasn't a problem, I never used 1G boxes smaller than 20 cuin. One contractor insisted on 4x4x2-1/8 boxes w/mudrings! I'll play if they pay!
Your right, when you start getting into homes with 2500 sq.ft., or more the runs start to become very long and voltage drop can really be a problem. I use the big 4-S too, but if there is a fil problem I will gang 2 x 3 x 3 1/2 together and never have had a problem with it. But as far as limiting the use to just no.12 for residential, I could put up with it, but i'd prefer not to. I do know in the Ccleveland area they can use no wire smaller than No.12, But even with No.12 at about 85 feet and your at the required 5 % voltage drop at 15 amps.
