Update....
Since I had to take off the side plate anyways, I ordered a Wolf mainspring. The lightest weight one. I performed the surgery yesterday, and it went off without a hitch. Huge improvement over the factory spring. It really is some sort of lawyer thing.
To compare the factory spring with the Wolf spring is revealing. The factory spring is thick and unrefined, and the Wolf spring is thin and nicely machined.
