The Melee Cross features a new lower RG version of the Melee symmetric core matched with our new Savvy Hook Solid reactive coverstock to provide maximum versatility with more traction in oil. The Melee Cross revs strong in the mid-lane and produces greater entry angle to the pocket for superior pin action on medium to heavy oil lane conditions.
