I basically have enlarged the 'gullet', fluted the back of the cutter a tad, cleared it out a bit under and inside the cutter, and thinned the top and back of the raker slightly and put an angle on the cutter that you can easily maintain in the field. This is about an hour of work on a 32-36" chain. The photo doesn't do it justice, the inside of the cutter and the tip of the raker have more work done than you can see here due to the angle and the flash. I am still messing around with grinding, so they may look different in the future. I have decided to leave the straps alone as much as possible, but I may grind off and angle the back of the cutter just a tad to see if there's a difference.
Compare that to a full race chain:
