Phil,
First off, good luck with your new venture. I wish you much success (your success will translate into our success).
I would like to see a good medium condition, benchmark ball that could be adjusted for heavier/medium or lighter/medium with tweaking. This would be a good first ball that you could start building an arsenal from. It should be solid resin, maybe a solid/pearl hybrid, with a coverstock that is both durable and thick. The cover should be able to get through the heads to save energy and also be able to handle carrydown. I would like to see a symmetric core with a low RG and medium Diff. It should also have a high Coefficient of Restitution (does anybody still use this term?). Thanks for all of the sharing of information you do on this board and for asking for our input. Good luck....John
