The INTEGRA I DRIVE III Offset driver head 460cc (the square head) is the BIG brother to the original I DRIVE head. This head will give you MAXIMUM reduction in head twisting at impact. The I drive head III is similar to the Quadratic and I Drive head but with no Carbon fiber crown and is made from 90ti-6al-4v titanium. The I Drive III has longer back heel area for even better control. Head is very forgiving for all levels of golfers.
