I saw to the line as well, with hand tools and power tools. I only score in hardwoods. If you look at the shoulders of old frames you don't generally see chisel marks (because they were sawn). One advantage of square rule framing is the housings (girts, braces, studs, all non-through housings that is) hide potential shrinkage. Drawboring takes care of some as well, and then you don't need 15 comealongs (or any really). I'm still practicing with the chain saw on the end of tenon cuts.
