Hi TT - put my new 818 H1 in play this week for the first time A1 setting with draw weight. Hit two phenomenal shots with it and was in awe of the majestic-high ball flight. That said, both times i thought i had hit the hosel because of the sound. It sounds like a wood 2x4 at impact. Very different than what i was used to with my 915 hybrid. Is this normal? Thanks. Justin
