Buddy,
Don't let me dissuade you, you MAY have the next great idea! If you believe you do have one, probably your best bet would be to contact a "grass roots" company, not one of the "big boys" in the industry.
One thing is, there are now so many "proven" cores out there that have been dis-continued by their original owners and the rights sold to smaller companies like SPORTS-TEC and CAFFEINE sports that it would be hard to get a "new" idea by an unknown person looked at.
Big companies ( like Storm or Ebonite ) have plenty of money to spend on R&D and don't need our ideas. Smaller companies have limited capital and can't afford to "bet" it on some unknown, untested theories of an untrained "lay" person.
All that being said, try visionary. They seem to be very customer/consumer oriented and MIGHT at least give your ideas a thought or two if they look promising.
Other than that, maybe MOTIV or SEISMIC might take a look, but you would just have to find out how to get in touch with their design/tech department to find out.
