Since the OP of the thread made mention that he is trying carbons now for the 1st time this year and is already thinking of switching brands I thought the question was more than appropriate.As for calling Easton I have no need as my Easton Rep Jared Washburn was at my shop less than a month ago and I have a list of what shafts are not made in the USA.The Beman ICS shafts are made in the USA!Perhaps someone is misleading you? Check and reveal your source as I did and we can continue from there.Good luck chasing those longbeards..GSLAM95
