That's not true, but it's likely he didn't know that. All you need to make
the photo pickup you currently have work with the MSD is a Crane XR700 box.
The XR700 uses the same pickup as the XR3000, but the output of the XR700
can be used to trigger the MSD box.
Even triggering the MSD with points worked out quite well for me, much
better IMO than the XR3000. But your dizzy needs to be in good shape, as
any shaft wobble will still show up as spark scatter.

I've never tried the Pertronix, but conceptually I like the XR700 (as a
trigger for the MSD) better. The Pertronix is better than points, but is
still somewhat sensitive to shaft wobble and I've heard that as little as
.020" TIR wobble can cause misfiring (not to mention making the pickup rub
on the point cam). The Crane should be able to deal with 10 times that much
wobble and still deliver at least some sort of spark.
