I think the
callaways are whats know as 'Drop Forged' this means that the initial formation of the head is a standard casting but then they are traeted to hammering like in forging, this smoothes out the texture of the steel and gives it slightly more of a forges characteristic. By the way, there is little or no difference in feel between forged and cast, thats a gimmick that the forged club manufacturers latched onto. Cast
clubs can be made to behave just like forged just as forged can be made to behave like cast, its all related to the final treatment stages.
For the record,
Callaway Wedges are very poor. All the guys I know who tried them got rid of them in favour of vokeys or cleve's within months. The local pro cant give them away.
