I understand what you're saying but it's not the answer I'm looking for.  I have a history with strong rankings for product pages but am having a discussion with someone else who believes it should be worded differently.  I know that rankings and CTR don't always work hand-in-hand when it comes to title tags and changing them later could cause issues with ranking.  What I'm looking for is specifics from people who have tried it both ways and have an opinion or who have done it a certain way and have had lots of success.  I appreciate your responses, but I'm looking for a specific "I've done it this way and believe it's right based on...."
