Here is the the committee I would form to consult for the best and most economical way to slow the cars down. NHRA should fund this and be in a support role only. These people are a wealth of knowledge and should be utilized for the betterment of the sport.
Don Garlits - start with Big Daddy for the rational side of things.
Dale Armstrong - for his innovation and talent.
Dick LaHaie - for his independent ideas and running his own team for years, then working for the biggest teams.
Don Prudhomme - for his vision and ownership history and working with major sponsors.
Whit Bazemore - former small team owner, driver, and a younger view with no ties to anyone.
Let these people assemble a complete team and direct the testing to come up with a way to use current parts yet keep costs down as much as possible.
Then, keep NHRA, DSR, JFR, AJ, etc, all the manufactures and anyone connected with the current status quo out of the testing and meetings.
Let this group make the final recommendations and live with it.
Remember, the drivers and cars are the Stars, not the "freak show" numbers we are so obsessed with.
