Thanks for the input, guys! To get a second opinion, Mary & I flew the plane yesterday, and she gave it the "yoke-mounted GPS test". Previously, her yoke-mounted GPS vibrated so badly that during climb-out that she had to hold it still with her hand to read it - now it doesn't vibrate as much during climb-out, although at cruise it's about the same.
We didn't experience the take-off shudder from last week during either take-off yesterday. So maybe I'm just noting different vibes - at least from Mary's point of view there's some improvement during climb-out! Overall, I don't think there was any cabin improvement, but maybe it's not as bad as I initially thought - I was hoping for a big improvement, which didn't happen. We'll check prop tracking during next annual. Paul

Prop track takes just a few minutes to check.With the plane parked in the hangar, place a block on the floor just behind the front prop. Let one blade just barely touch the block. Make sure mags are off, then turn the prop and bring the other blade down to the block. If they are in track, then the second blade will be where the first blade was in reference to the block. If not, let's say you have an 1/8 inch difference, then you have a track issue. Sometimes track can be corrected by moving the prop a bolt hole or two left or right on the flange.
