I am no expert by any means, but, if he can get a total timing of at least 32 degrees, how is it possible for him to get any pinging at 15 degrees initial timing. I thought timing was timing. The only reason not to have a big initial timing was it would be too hard on the starter. If the starter can turn the engine over with 20 degrees initial, then go with 20. You would just have to be careful with your total timing concerning pinging or detonation. From what I have read, set your initial timing using a vacuum guage. At idle (800-900 rpm), turn the distributor until you get the highest vacuum reading. That point will be your best initial timing. Now, if that is too high for your starter to turn over the engine, then back it off a little until the starter isn't stuggling too much.

I have a 63' co and it likes 18 degrees initial and 39 degrees total.
