Part of it is curiosity, but part of it also is wondering if the 7000 vs 1500 ft is such a big difference that I should consider different drivers or at least different setups on the same driver depending on which location I'm playing. To add to the difficulty, my high altitude course often has soft, wet fairways which favor carry over roll while my low altitude courses most often are hard and allow for a long roll. Both conditions are pointing to very different setups on my driver.
