Most Shaft companies send in review samples. Korea Hidden Technology never replied to the request for review samples. A great many golf fitters have professional subscriptions to my software and were interested in seeing the profile of the autoFlex shafts. One of them provided a shaft to be added to the database. The profile is no longer hidden.
