Thanks Again Scooter123!
Surprised you say a 4 lb SA trigger is about it for the Model 60-10 but I'll find out I guess. In any case unlike the 460, the DA pull will have priority here. Going for as light and smooth DA action as possible. Got a Jerry Miculek S&W trigger job dvd coming, hoping to learn some tricks from him.
Totally agree with you about inducing a negative angle to the sear interface, you MUST always retain a positive angle there of the gun will become dangerous. Any improvement done to the interface must come from either a reduction of surface area, a smoothing of the surface areas, or both. Nice thing about the S&W side plate design is that it's lets you inspect the interface under a microscope while actually installed in the gun. Then you can see exactly what you can get away with and what you can't.
I'll let you know how things come out.
