Quicker roll with fusion rxweve taken the most legendary insert of all time thats the best feeling best selling with the most tour wins and combined it with unbelievable new roll technology for the fusion rx insertits where feel meets roll as we couple the white hot insert with ultra thin stainless steel mesh and our patented metal x roll pattern there are no compromises and it has faster roll than the white hot insert so it reduces skidding and gets the ball into a pure roll fastermajor
