I decided to try a 315 degree drilling and it requires a 0-1" pin AND a light top weight. I never knew how hard it was to get such a ball (unless you don't want it, of course). I emailed Buddies with a list of balls that I thought appropriate for my needs and Chris answered me that only a Sonic-X pearl was available with those specs. Told me to just order it online and put what I wanted in the COMMENTS section. I did so and Bill, Chris's partner, called me at home to check on my order. I told him Chris had told me what to do.
2 days later, delivered by UPS in the midst of a snow-storm, here it sits.

These two guys are just beyond belief.

If your pro shop cannot or will not get exactly what you want or need, I'd strongly urge you to try them.
