First off, items left blank are being tested or in the process of being retested. I tried to test the most recent build date to give you the most current results. Disclaimer: of all the reviews I've done, the shuttle review was the hardest. There are many variables that can affect the performance of the shuttle: Temperature Humidity Age of the Shuttle Exposure to the Elements Feather Consistency from the Factory Bad Batch, Good Batch Different Grades for Different Countries If your findings do not agree with mine, don't worry. Again, there's such a wide disparity among all the shuttles. I would not be surprised if there are differences in results, as I have found on quite a few occasions. So, you should use this review as a guide or for comparison purposes only. And like everything else on BC, take it with a grain of salt.
