Yesterday I picked up 6 Carbon Express Mayhem 250 arrows. Re-fletched them with NAP 2" quick spin wraps. Really good accuracy and seem slightly faster than the easton epics. Went out and shot them just to make sure no flyers. The 250 were with-in my length and poundage range according to their chart. Son and I also installed a string dampener on our bows this year. Guess who bought son's??? We went with Vibracheck backstop models.
