I'd get a stainless Taurus 651, myself. BUT, I have a great shootin' 3" Taurus 66 I really like a lot, very accurate, just not a pocket gun. I don't think any shootable .357 is really good as a pocket gun as I want a steel frame. I've fired a 12 ounce scandium Smith once. Not for me with full house magnums, rather just get a .38 ultralite for less money.
The 3" medium frame 66 is a belt gun, but it's an easy gun to carry, easier gun to shoot, is very accurate, and offers one more round. It's JMHO and YMMV, but I like the medium frame 2.5-3" when compared to the J frame size guns. For the pocket, I'd rather have an ultralite/airweight .38. I'd have rather had a round butt on the 66, my only gripe. The 651 is a steel gun, though, and pocketable if you don't mind the weight. It's a concealed hammer gun, too, which gives it a smoother pocket draw, but can still be fired SA.
You mention finishing shots? I was carrying my 3" blued 66 the day I came across this thing at 15 yards in an oak mott. One shot, one kill.
I'm proud for you if you prefer your Smiths, but don't think that a Taurus can't gitter dun. I have three fine examples.
