Tom, I pretty much agree with all you have said.
When I set up using my Cart Align, I use a tiny nylon thread around the turntable spindle to locate the spindle bearing to tone arm pivot. As you pointed out, having the mirror helps me do the other parts of the setup and I like the sound I get from the Cart Align formula.
The one thing on the Graham tool that seems to be missing from the discussion is the alignment of the cartridge in the head shell. As I remember (from the three I've owned) the user presses a plastic device against the cantilever to sight the correct overhang. While in theory this appears to be a clean solution, it does not take into consideration the exact stylus pressure during playback, which effects overhang and VTA.
I agree with your assessment of the Graham tool for setting pivot to spindle distance. I got where I could feel the side to side pressure of the unipivot and could get pretty close, but never 100%.
I also owned the Dennison and as you pointed out, the spiked metal outrigger allowed for very good sighting of the pivot to spindle, much easier than the tiny thread on the Cart Align system. I could never "read" the Dennison once I had it in place and for that reason, sold it as I did the WallyTractor.
Truth is, I keep my set up tools to help others (which I do all the time). My Walker does not benefit from any of these, but I enjoy hearing all turntables and arm setups because I love analog so much.
