Do You Have a Favorite Disk to Set VTA/SRA?

Interesting pictures of stylus shapes.

So - Wouldn't the average audiophile's life be easier with a spherical stylus? Just set the overhang and a reasonably parallel arm tube and you're pretty much done. I wonder how compromised the sound would be if a high-quality spherical stylus were put on a good cartridge, say $1500-$2500. This is of course for those not willing or able to achieve perfect alignment and reset VTA for each record. I haven't done a survey, but I think sphericals are used on lower-priced carts to keep the price low, but why not on a better cart? What do you think, Doug?
